SW-PFL-1550 Series of Narrow Line-Width Fiber Pulsed Laser
Classification:
The SW-PFL-1550 is a series of 1550nm narrow line-width fiber pulsed laser, that designed specifically for coherent heterodyne detection systems.This type of laser can generate a single pulse energy up to 300 μ J or pulses with peak power up to 750W. The pulse is linearly polarized, with very high polarization extinction ratio, long coherence length, low noise and excellent output beam quality. The SWPFL-1550 series fiber laser can work around the clock in most harsh environment, making it an ideal laser source for various wind measurement fields.
