CoLIA 1550nm Long Pulse Single Frequency PM Fiber Amplifier

The CoLIA 1550nm long pulse single frequency polarization maintaining fiber amplifiers of Connet are designed for long pulse (100ns-2us) application. This modularized fiber amplifier is an eye-safe wavelength amplifier and the max pulse energy can be up to 120uJ.


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