    Product Description:

    The 1550nm long pulse single frequency polarization maintaining fiber amplifier of Connet Laser is designed for long pulse (200ns-2us) application. This modularized fiber amplifier is an eye-safe wavelength amplifier and the max pulse energy is up to 120uJ.
    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. By virtue of the multi-stage optical amplification in optimized design, this series of amplifiers can suppress the nonlinear effects such as stimulated Brillouin scattering (SBS), realize high pulse energy, maintain the spectral character of the signal light and obtain the near diffraction-limited beam quality at the same time. They are the ideal amplifiers for Doppler wind-measurement LiDAR.
