Description

1064 nm Pulsed Laser Source Module – Compact, High-Power Seed Laser for Pulsed Fiber Systems

The 1064 nm Pulsed Laser Source Module is a compact, diode-based pulsed laser designed specifically for demanding industrial, research, and OEM applications. Operating in the 1032–1080 nm wavelength range with a typical center wavelength of 1064 nm, it provides high peak power up to 1 W in a space‑saving module form factor. This source is engineered as an ideal seed laser for pulsed fiber lasers, combining short pulse capability, narrow spectral width, and excellent stability in one integrated platform.

Built around a high‑performance semiconductor laser diode optimized for pulsed operation, the module uses direct current modulation through a carefully designed pulse driver circuit. This architecture enables pulse widths from 1 ns to 1 µs, with fast rise and fall times around 2 ns, supporting repetition rates up to 1 MHz (1000 kHz). Such a wide operating window allows users to fine‑tune pulse parameters for time‑resolved measurements, nonlinear optics experiments, and fiber‑based sensing systems. With a spectral width (FWHM) of ≤1 nm and side‑mode suppression ratio of at least 20 dB, the source delivers clean, well‑defined pulses suited for precision optical test and measurement tasks.

For seamless integration into larger systems, the 1064 nm pulsed laser source adopts a robust module package powered from a standard 12 V DC supply. It incorporates an industrial‑standard RS‑232 control interface that allows full parameter control via upper‑computer software, making remote configuration, automation, and monitoring straightforward. A built‑in signal generator simplifies stand‑alone operation, while an external TTL trigger input enables synchronous pulsed output driven by user electronics, which is crucial in timing‑critical setups such as gated detection, pump‑probe experiments, and synchronized multi‑laser platforms.

The optical output is provided through single‑mode fiber (with polarization‑maintaining fiber optional) and a standard FC/APC connector, ensuring stable beam delivery and low back‑reflection into the source. Output isolation is integrated to further protect the laser diode from return loss and environmental perturbations. With more than 1 m of fiber pigtail as standard and other connector options available on request, the module can be easily incorporated into fiber‑based measurement benches, interferometers, and distributed sensing networks. This fiber‑coupled configuration mirrors the approach used by many advanced 1064 nm seed sources and pulsed laser modules in the broader photonics market.

Stability and reliability are central to the design. The module offers excellent output power stability, typically within ±0.5% over 15 minutes and ±1.0% over 8 hours after warm‑up under standard laboratory conditions. This level of performance is comparable to or better than many similar pulsed diode sources used in precision metrology and optical characterization systems. The output power can be adjusted from 0 to 100% using both coarse and fine control modes, allowing users to set and maintain the optimal operating level for sensitive detectors, nonlinear crystals, or fiber components without over‑illumination or damage.

With a maximum power consumption of up to 30 W and an operating temperature range from 0 to 50 °C, the module is well‑suited to integration into OEM systems and 24/7 setups where long‑term stability and low maintenance are required. The compact housing, typically around 150 mm × 125 mm × 25 mm, allows straightforward installation in crowded optical racks, enclosures, or portable instruments. Its robust construction and extended storage temperature range from −40 to 85 °C support reliable operation in diversified environments, from standard labs to industrial test lines and field‑deployable instrumentation.

Typical application areas include use as a seed laser for pulsed fiber lasers, time‑resolved test and measurement, optical fiber sensing (including distributed sensors and interferometric detection), spectral analysis, and a wide range of general laboratory experiments requiring a stable, pulsed 1064 nm source. Thanks to its combination of short pulse operation, high peak power, narrow linewidth, fiber‑coupled output, and flexible control interfaces, this 1064 nm Pulsed Laser Source Module offers a highly versatile platform for developers, system integrators, and researchers working in advanced photonics and laser‑based measurement systems.
