Abstract

We have describe a simple diode-side-pumped high-power and high efficiency Nd:YAG laser that produces 240 W of power continuous-wave(CW) with 33% optical-optical efficiency. We used the technology of diode laser close-couple to realize high pumping efficiency ,We measured the thermal lensing focal length to design the laser resonator, which decrease the rod thermal effect. By changing the resonator parameters ,we can adjust the fundamental mode size and the output beam quality.
