A 658-W VCSEL-pumped rod laser module with 52.6％optical efficiency
文献摘要：
A high-efficiency and high-power vertical-cavity surface-emitting laser(VCSEL)side-pumped rod Nd∶YAG laser with temperature adaptability are demonstrated.The VCSEL side-pumped laser module is designed and optimized.Five VCSEL arrays are symmetrically located around the laser rod and a large size diffused reflection chamber is designed to ensure a uniform pump distribution.Furthermore,the absorbed pump power distribution of the rod is simulated to verify the uniformity of the pump absorption.Finally,a proof-of-principle experiment is performed in short linear cavity laser with single laser module.A continuous-wave output power of 658 W at 1064 nm is obtained,the corresponding optical-to-optical efficiency is 52.6％,and the power variations are±0.7％over 400 s and±3.1％over the temperature range from 16℃to 26℃.To the best of our knowledge,this is the highest output power and the highest optical-to-optical efficiency ever reported for VCSEL pumped solid-state lasers.By inserting a telescopic module into the cavity and optimizing the TEMoo mode volume,the average beam quality is measured to be M2=1.34 under an output power of 102 W.The experimental results reveal that such a high power rod laser module with temperature stability is appropriate for field applications.
