1550nm Long-Pulse Single-Frequency Polarization-Maintaining Fiber Amplifier CoLIA-1550-M-SF-LP
Shanghai Hanyu’s 1550nm long-pulse, single-frequency polarization-maintaining fiber amplifier is a modular device for 100ns-2us pulses. Its eye-safe operating wavelength and high pulse energy provide output up to 800uJ. Optimized multistage amplification supports single-frequency sources with linewidths down to the kHz level, suppressing nonlinear effects such as stimulated Brillouin scattering (SBS) while preserving spectral characteristics. Nearly diffraction-limited beam quality and a high polarization extinction ratio (PER) suit coherent Doppler lidar and similar systems.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
