Description

793/808/915/976/1064 nm MM Fiber Coupled High Power Pump Laser

The 793/808/915/976/1064 nm MM Fiber Coupled High Power Pump Laser from DK Photonics is an industrial-grade pump source designed to drive modern fiber laser systems and demanding laboratory setups. Built around a high-performance semiconductor laser chip and a carefully engineered constant current driver with TEC temperature control, this laser delivers stable high optical power through a 105/125 µm multimode fiber. With available output powers of 5 W, 10 W, 25 W, and 50 W, it is well suited for fiber laser pumping, medical and biomedical research, materials processing, and a wide range of OEM integration tasks that require reliable, long-term operation.

The laser operates at popular pump wavelengths (793, 808, 915, 976, and 1064 nm), making it compatible with a broad spectrum of doped fiber gain media commonly used in high-power fiber lasers, amplifiers, and solid-state laser pumping. Thanks to its integrated TEC regulation and constant current drive electronics, the unit offers excellent power and spectrum stability, with long-term power fluctuations within approximately 3% over 8 hours and wavelength stability within ±3% (typical) of the nominal center wavelength. This performance aligns with pump modules used in high-end fiber laser systems worldwide, where stable, repeatable operation is critical for both research and production environments.

Output is delivered via a 105/125 µm multimode fiber with a numerical aperture of 0.22, providing efficient coupling into fiber laser cavities, combiners, and delivery fibers commonly found in industrial and scientific setups. The standard configuration uses bare fiber output, which is preferred for permanent integration and splicing into larger systems. For lower-power configurations where quick connect/disconnect is desirable, an SMA optical connector can be optionally specified. This flexibility allows the module to be adapted to both fixed, high-throughput installations and more dynamic laboratory configurations where reconfiguration is frequent.

To accommodate different integration scenarios, the pump laser is available in both desktop and compact module versions. The desktop version includes button control on the front panel and an integrated universal AC power supply (100–240 V AC), making it ideal for standalone use on optical benches, in university labs, and in R&D facilities. The module version is optimized for OEM and system-level integration, powered from a 12 V DC supply with lower power consumption, and controlled via an RS232 communication interface through a DB9 connector. This modular design enables straightforward embedding into larger fiber laser platforms, medical systems, or process tools while retaining precise control over output power and operating conditions.

The robust thermal and mechanical design supports continuous operation over a wide environmental range, with an operating temperature window from -5 °C to +55 °C and humidity from 0% to 70%. Such resilience makes the pump laser suitable not only for controlled laboratory environments but also for more demanding industrial and field-deployed systems. In applications such as materials processing, laser marking, precision cutting, or medical and biomedical instrumentation, stability of both power and spectrum is essential to ensure consistent process quality and reproducible experimental results. This pump laser addresses these needs with carefully controlled drive electronics and thermal management, comparable to similar high-power MM fiber-coupled pump sources used across leading photonics and fiber laser platforms.

With a well-defined ordering structure covering wavelength, power level, fiber type, and package format, the series can be easily configured for specific system requirements. Users can select the wavelength that best matches their doped fiber or solid-state gain medium, choose the required output power to achieve the desired system performance, and specify either the desktop or module form factor based on whether plug-and-play operation or full OEM integration is preferred. For specialized or non-standard configurations, custom options are also supported, enabling tailoring of parameters such as output power, packaging, or interface to fit unique research and industrial needs. The result is a versatile, high-reliability pump platform for building and upgrading fiber lasers, amplifiers, and advanced photonic systems.

The laser uses a constant-current driver and TEC (thermoelectric cooler) control to ensure power fluctuation below 3% and wavelength stability of ±3 nm (±10% wavelength accuracy for 915 nm). It comes with a 105/125 µm multimode fiber with NA 0.22 and offers either bare fiber output (with an optional SMA connector for low power versions), and is available in both compact module and benchtop (desktop) packages.
What are the typical applications of this multimode fiber coupled high power pump laser?
This MM fiber coupled high power pump laser is mainly used as a pump source for fiber lasers and fiber amplifiers, a common use case in industrial and scientific systems. Typical applications include: 1) Fiber laser pumping at 793 nm, 808 nm, 915 nm, 976 nm, and 1064 nm; 2) Biomedical and life science applications, such as fluorescence excitation, optical trapping setups, and phototherapy systems where high-power diode sources are needed; 3) Materials processing, including plastics welding, soldering, thin-film processing, and as a pump for high-power ytterbium- or erbium-doped fiber lasers used in cutting, marking, and engraving; and 4) General laboratory research and production testing that require stable, high-power, fiber-delivered diode light sources. Similar high‑power multimode pump modules found on FindLight and other laser marketplaces are used in essentially the same application areas.
What configuration options are available for wavelengths, output power, and package type?
The product is organized using a part number format P/N: ①-②-③-④-⑤, where each field corresponds to a specific configuration. ① is the product series (MMHPL – Multimode High Power Pump Laser). ② is the operation wavelength, which can be selected from 793, 808, 915, 976, or 1064 nm. ③ is the output power, with standard options of 5 W, 10 W, 25 W, and 50 W; custom power levels can be requested. ④ specifies the fiber type; the standard is MM 105/125 µm multimode fiber with NA 0.22. ⑤ is the package type: "M" for compact module and "B" for desktop (benchtop) unit. In addition to these standard options, DK Photonics can customize some parameters on request, which is consistent with similar high-power pump diode modules listed on FindLight and other laser suppliers.
What are the key optical and stability specifications of this high power pump diode?
For the standard configurations, the center wavelength options are 793 nm, 808 nm, 915 nm, 976 nm, and 1064 nm. The wavelength tolerance is typically ±3 nm for the 793, 808, 976, and 1064 nm versions, while the 915 nm version is specified with ±10% accuracy. The spectral width is about 3 nm (typical) for 793/808/976 nm models and about 6 nm for 915 nm versions, which is typical for high-power multimode pump diodes used for fiber laser pumping. Output power can be 5, 10, 25, or 50 W (and customized levels) at the fiber output. The short‑term power stability over 15 minutes is ≤ ±0.02 dB (about 1%), and the long‑term stability over 8 hours is ≤ ±0.05 dB (about 3%), which is in line with or better than many comparable multimode pump modules on the market. The fiber output is through a 105/125 µm multimode fiber with NA 0.22, with bare fiber as standard and an optional SMA connector available for low‑power models.
What are the differences between the desktop (benchtop) and module versions, and how are they controlled?
Both the desktop and module versions share the same core laser diode and optical performance but differ in form factor, user interface, and power input. The desktop (benchtop) version integrates its own AC power supply and front-panel controls. It operates from 100–240 V AC with power consumption below 120 W. Control is via front-panel buttons, making it suitable for laboratories and test setups where manual operation is needed. The module version is a compact OEM unit meant for integration into larger systems. It typically runs from a 12 V DC supply with consumption under 60 W. Control and monitoring are performed digitally through an RS‑232 interface, using a DB9 female connector (or other serial/PC interface as specified). DK Photonics also offers PC monitoring software, which allows remote control and real-time monitoring of parameters such as drive current, output power, and temperature, similar to other OEM pump diode modules available on FindLight and from global laser manufacturers.
What are the electrical and environmental operating conditions for this pump laser?
The pump laser is designed for reliable operation in standard laboratory and light industrial environments. The operating temperature range is −5 °C to +55 °C, which allows use in slightly cooled or elevated temperature environments when proper ventilation is provided, matching ranges seen in many comparable pump diode modules. The allowable operating humidity range is 0–70% (non‑condensing recommended). The desktop version is powered by 100–240 V AC mains and consumes less than 120 W, while the module version operates from a 12 V DC supply and draws less than 60 W. As with similar high‑power multimode pump diodes, users should avoid condensation, ensure good thermal management, and respect any derating that DK Photonics may specify for continuous full‑power operation near the temperature extremes.
How do I order or customize a DK Photonics MM fiber coupled high power pump laser, and what information should I provide?
To order a standard configuration, you select the part number according to the format ①-②-③-④-⑤. For example, a typical code might specify the MMHPL series, a given wavelength (e.g., 976 nm), the desired output power (e.g., 25 W), the standard MM 105/125 µm fiber, and the package type (module or desktop). When sending an inquiry, it is recommended that you provide the full P/N along with a clear written description of your needs (wavelength, power, fiber length and connector, package type, and control interface). For custom configurations—such as non‑standard power levels, special fiber types, different fiber lengths, or alternative connectors—DK Photonics asks that you provide detailed requirements so they can confirm feasibility, price, and lead time. This process is similar to ordering other custom pump diode modules listed on FindLight and from other manufacturers: specify wavelength, output power, fiber core/cladding/NA, connector type, package/footprint, operating mode (CW or pulsed, if applicable), and any integration or control interface preferences.
