摘要
介绍了采用多波长耦合和偏振耦合的方式实现千瓦级高功率半导体激光输出的方法。通过光束整形的方法，实现了快慢轴光束参数积对称化，激光器输出激光光束质量小于12 mm·mrad，超过了全固态激光器的光束质量；激光器光-光转换效率达到87.5%。并通过智能化控制，实现了不同波长、不同功率、不同脉冲宽度的激光输出。
Abstract
Kilowatt high power diode laser is reported with the ways of multi-wavelength and polarization coupling. The fast and slow axis beam parameter product is symmetrized by the method of shaping with the beam quality better than 12 mm·mrad and all-solid-state laser. 87.5% optical-optical efficiency of the high power diode laser is obtained. Through intelligent control, the diode laser can be outputted with different wave lengths, powers and pulse widths.
