Abstract

We reported pump uniformity study of a side-pumped DPSS laser, which produced CW output of 30 W with a proper uniform pumping. An JR camera was employed to study the pump energy distribution as well as the thermal effect inside the laser crystal. Theoretically simulated energy distributions were compared with the experimentally measured JR images. Jt is found that the JR imaging technology is an effective method to study pump uniformity of side-pumped DPSS lasers, and uniform pumping is very essential to achieve a good beam quality and a wider stable operating range for high-power DPSS lasers.
