Techwin 1550nm long pulse single frequency polarization maintaining fiber amplifiers are designed for long pulse (200ns-2us) application. These modularized fiber amplifiers are an eye-safe wavelength amplifier and the max pulse energy is up to 400uJ.

Techwin 1550nm long pulse single frequency polarization maintaining fiber amplifiers are suitable for amplifying single frequency narrow-linewidth source. The linewidth can be narrowed to kHz level. By multi-stage optical amplification of optimized design, this series of amplifiers suppress nonlinear effects such as stimulated Brillouin scattering (SBS), realize high pulse energy, maintain spectral character of the signal light and obtain near diffraction-limited beam quality at the same time, which are ideal amplifiers for Doppler wind-measurement LiDAR.
