1450 nm Raman Amplifier Pump Laser – High‑Power, Ultra‑Stable Fiber Laser Source

The 1450 nm Raman Amplifier Pump Laser from DK Photonics is a precision-engineered, single‑mode fiber laser source designed specifically for Raman amplification and fiber laser pumping applications. Built around a high‑performance butterfly semiconductor laser diode, this source delivers high output powers up to 500 mW in the 1425–1465 nm band, with exceptional power and wavelength stability. By integrating a professionally designed low‑noise driver and TEC temperature control, the unit ensures reliable, long‑term operation even in demanding laboratory and system‑integration environments.

Operating at selectable center wavelengths of 1425, 1435, 1455, or 1465 nm with MHz‑level wavelength accuracy, this laser is optimized as a pump for fiber‑based Raman amplifiers and as a versatile seed or pump source for nonlinear optical experiments. The high spectral purity and low intensity noise make it suitable for telecom C‑band and L‑band Raman amplification, distributed Raman amplification in long‑haul fiber systems, and scientific research where precise control over the pump wavelength and output power is critical. Short‑term power stability better than ±0.02 dB and long‑term stability better than ±0.05 dB support highly repeatable measurements and consistent system performance.

To simplify integration into a wide range of setups, the 1450 nm Raman pump laser is offered in both desktop and compact module configurations. The desktop version provides user‑friendly front‑panel control for quick setup, making it ideal for R&D labs, prototyping, and educational environments. The module configuration, with RS232 control and a DB9 interface, is tailored for OEM and system‑level integration where remote operation, automation, and compact footprint are priorities. Both versions are built around SMF‑28e single‑mode fiber output with an FC/APC connector, ensuring low back‑reflection and easy connection to standard telecom and photonics components.

The laser operates over a broad temperature range from −5°C to +55°C and a humidity range from 0% to 70%, enabling stable performance in typical indoor and light industrial environments. The desktop unit uses a universal 100–240 V AC power supply with power consumption under 30 W, while the module operates from a 5 V DC supply with power consumption below 15 W—ideal for space‑ and power‑constrained applications. With flexible output power options (200 mW, 350 mW, or 500 mW) and multiple wavelength choices, the 1450 nm Raman Amplifier Pump Laser provides a robust, scalable platform for building advanced Raman amplifiers, fiber laser systems, and nonlinear optics experiments.

Frequently Asked Questions

What is the DK Photonics 1450nm Raman Amplifier Pump Laser and what is it used for?
The DK Photonics 1450nm Raman Amplifier Pump Laser is a high‑power single‑mode semiconductor laser source with fiber output, designed primarily as a pump for fiber Raman amplifiers and fiber lasers. It operates in the 1450 nm band (with options at 1425, 1435, 1455, and 1465 nm) and is built with a high‑performance butterfly laser diode, precision TEC temperature control, and a low‑noise driver. Typical applications include fiber Raman amplifiers in optical communication systems, pumping of specialty fiber lasers, and research in nonlinear fiber optics and Raman scattering.
What center wavelength and output power options are available for this 1450nm Raman pump laser?
This Raman amplifier pump laser is available at four center wavelengths: 1425 nm, 1435 nm, 1455 nm, and 1465 nm, with a wavelength accuracy of ±3 MHz. Standard continuous‑wave output power levels are 200 mW, 350 mW, and 500 mW at the selected wavelength. DK Photonics can also provide customized power levels within this range on request. All standard versions use SMF‑28e single‑mode fiber with an FC/APC connector for low back‑reflection, which is typical for Raman pump lasers used in telecom and fiber laser systems.
How stable is the output power of the DK Photonics 1450nm Raman pump compared with similar Raman pump lasers?
The DK Photonics 1450 nm Raman pump laser offers high power stability, with short‑term power stability of ≤ ±0.02 dB over 15 minutes and long‑term stability of ≤ ±0.05 dB over 8 hours under constant operating conditions. These values are competitive with many telecom‑grade Raman pump modules from other manufacturers and are suitable for applications where gain stability is critical, such as distributed Raman amplification in long‑haul fiber links, precision fiber sensing, and laboratory nonlinear optics experiments. The integrated TEC control and low‑noise driver help maintain stable optical output over the specified operating temperature range.
What package options and control interfaces are offered for the 1450nm Raman Amplifier Pump Laser?
The laser is available in two package types: a desktop unit and a compact module. The desktop version includes push‑button operation on the front panel, an internal AC power supply (100–240 V AC,
How do I specify and order a DK Photonics 1450nm Raman pump laser correctly?
DK Photonics uses a structured part number format: ①‑②‑③‑④‑⑤. For this product, key options are: ① FL (fiber laser series), ② operation wavelength (1425/1435/1455/1465 nm), ③ output power (200/350/500 mW), ④ fiber type (S28 for SMF‑28e), and ⑤ package type (M for module, B for desktop). When requesting a quote or placing an order, specify the exact center wavelength, power level, fiber type, connector (standard is FC/APC), and package type. If you require non‑standard specifications (different fiber, connector, power, or electrical interface), provide a detailed description so DK Photonics can offer a customized configuration.
What are the electrical and environmental operating conditions for the 1450nm Raman pump module and desktop versions?
The desktop version operates from a universal AC mains input of 100–240 V AC with power consumption under 30 W. The module version requires a 5 V DC supply with power consumption under 15 W. Both versions are specified for operation in ambient temperatures from −5°C to +55°C and relative humidity from 0 to 70% (non‑condensing). Within these conditions, the integrated TEC maintains the laser diode at a stable temperature to ensure wavelength and power stability. For best reliability, operation near the center of the temperature range and in a low‑vibration, dust‑free environment is recommended, similar to standard practices for telecom‑grade Raman pump lasers.
Is customization available for the 1450nm Raman Amplifier Pump Laser (wavelength, fiber type, connectors, or power)?
Yes. While standard configurations cover four center wavelengths (1425, 1435, 1455, 1465 nm), output powers of 200, 350, and 500 mW, SMF‑28e fiber, and FC/APC connectors, DK Photonics can customize many parameters. Common custom options include specific target wavelengths within the 1450 nm band, alternative output powers, different fiber types (e.g., PM or specialty fibers to match your Raman gain fiber), and other connector types (such as SC/APC). Interface options for the module and additional control features may also be available. To request customization, provide detailed requirements—wavelength, required power at fiber output, fiber and connector type, package style, and control interface—when contacting DK Photonics sales.
