Seed Lasers

What are Seed Lasers?

Injection seeding fiber lasers is a widely used mode-selection technique that uses a source laser to selectively reduce the laser’s gain threshold at that a specific wavelength.  This results in the laser’s output having the same spectral properties as the seed laser, therefore, improving its overall performance characteristics.    While this method can be used with both CW and pulsed fiber lasers, it is used mainly for producing narrow linewidth pulsed fiber lasers.  In this case, a single-frequency fiber laser is coupled into the fiber laser optical cavity and pulsed via a gain switching electronic driver board which can be triggered and timed to coincide with the q-switched fiber laser’s pulse.  This causes the fiber laser to lock onto the source laser’s exact wavelength due to the reduction in the laser’s gain threshold at that specific wavelength.   On this page, you will find a list of all of the single-frequency fiber lasers we offer for injection seeding pulsed fiber lasers.

Nps Series


The NPS series of ultrafast lasers is the ultimate solution for OEM integrators and researchers working with nonlinear optics applications like OPO pumping and narrowband Raman spectroscopy. The NPS series boasts remarkable features such as up to 10W average output power, <7ps pulse width, and a 40MHz repetition rate. The transform-limited operation, with a spectral width of <0.3nm, and accurate central wavelengths make these lasers a suitable candidate for highly efficient amplification by Nd-doped DPSS amplifiers.

R Series

R Series

The R series of wavelength stabilized singlemode and multimode laser diodes offer narrow linewidth output in wavelengths from 633nm thru 1064nm. This highly customizable series offers package options ranging from components as basic as a TO-56 or 14-pin BF packaged diodes, to OEM modules including electronics, to UL/CE and IEC certified turn-key systems. The R series is the perfect source for various markets, including chemical analysis, bio-medical, fiber laser, and scientific applications. 

Microchip Series

Bright Microlaser Microchip SB1 Laser

The Microchip series is a line of ultra-compact, passively q-switched, single longitudinal mode (SLM), narrow linewidth, DPSS lasers that offer exceptional performance in a compact form factor. The lasers feature pulse durations ranging from 400 ps to 2 ns, energy levels up to 80 µJ, and repetition rates up to 100 kHz. Available in wavelengths from the UV to the NIR, this series is designed for OEM integrators and researchers working with LIDAR, 3D scanning, LIBS, night vision, and more. The lasers offer both nanosecond and picosecond options and are interchangeable with the same form factor and electrical and software interfaces across wavelengths, making them a flexible and versatile solution.
