Abstract

Shortwave laser is more and more widely used in gated imaging, tracking and pointing, communication and other fields. For the requirement of 1550nm high power laser source, The paper analyzes the realization way, and realized the 1550nm high power laser lighting source. We use multichannel semiconductor laser coupling to realize the high-power light source, and uses fiber coupling to realize the uniform spot. On this basis, an extended collimator is designed, which achieves 10 times of high-power The beam divergence angle can reach 9 mrad to 90 mrad, and the RMS value can be less than 1/4 of the wavelength at each magnification of the wave phase difference, which can meet the needs of engineering application.
