CoLIS-LP Series1550nm Long-Pulse Single-Frequency PM Fiber Laser (Short-Range Integrated Version) CoLIS-1550-M-SF-LP
The Shanghai Hanyu CoLIS-LP series1550nm nanosecond long-pulse single-frequency PM fiber laser is a modular pulsed fiber laser for coherent Doppler wind lidar. It uses an eye-safe wavelength and true single-mode, linearly polarized output, with single-pulse energies up to the10uJ level. A proprietary single-frequency, narrow-linewidth fiber-laser seed provides linewidths down to the kHz level and very low phase noise to improve signal-to-noise ratio and lidar range. Cascaded acousto-optic modulators (AOMs) generate pulses with a high off-state rejection ratio and extinction ratios above100dB. An all-PM-fiber design provides high polarization extinction ratio (PER). A high-power three-port optical circulator can be integrated at the power output as required.

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.
