Thermal effect and laser characteristics of LD end-pumped CW Tm:YAG laser at room temperature
2017
Abstract This paper focused on the thermal effect and lasing characteristics of Laser diode (LD) end-pumped continuous-wave (CW) Tm:YAG crystal. The temperature-distribution of Tm:YAG rod was shown by using a software of COMSOL. The thermal focal length was calculated and the stability of the resonator was analyzed. Maximum output power of 6.71 W with output wavelength of 2014.2 nm and beam quality factor of M 2 = 3.6 was obtained.
