基于国产Nd:YAG陶瓷二极管侧面泵浦的高效、高功率准连续1064nm陶瓷激光器

Abstract

A high efficiency, high power diode-side-pumped quasi continuous wave (QCW) Nd:YAG ceramic rod laser at 1064 nm based on the domestic transparent ceramic is reported. The average output power of 961 W is achieved with double ceramic rods by means of a symmetrical convex-convex cavity. The optical-to-optical conversion efficiency is 38.3% and the slope efficiency is 45.3%. To the best of our knowledge, this is the highest level of efficiency achieved for the domestic Nd:YAG ceramic rod laser.
