The 1550nm long pulse single frequency polarization maintaining fiber amplifiers of Connet Laser are designed for long pulse (200ns-2us) application. These modularized fiber amplifiers are the eye-safe wavelength amplifiers and the max pulse energy is up to 120uJ@200ns.

The 1550nm long pulse single frequency polarization maintaining fiber amplifier of Connet Laser is suitable for amplifying single frequency narrow-linewidth source. The linewidth can be narrowed to kHz level.

Thanks to the optimized design of the multi-stage optical amplification, this series of amplifiers can suppress the nonlinear effects such as stimulated Brillouin scattering (SBS), realize the high pulse energy, maintain the spectral character of the signal light and obtain the near diffraction-limited beam quality at the same time, which are ideal amplifiers for Doppler wind-measurement LiDAR.
