Abstract

Lasing of an array of 30 single-mode laser diodes with different wavelengths is experimentally investigated in the scheme of spectral beam combining. The maximum lasing power of 7.2 W is obtained in the pulsed mode with the quality of the combined beam close that of a single diode at the total lasing spectrum width of about 40 nm and the spectral component line widths below 0.3 nm.

光束光谱组合下单模激光二极管阵列的激光特性

摘要

在光谱光束合并方案中，对30个具有不同波长的单模激光二极管的阵列发射进行了实验研究。在脉冲模式下获得的最大激光功率为7.2 W，在总激光光谱宽度约为40 nm且光谱分量线宽度低于0.3 nm时，组合光束的质量接近单个二极管的光束质量。
