A high efficient one-end-pumped TEM00 laser with optimal pump mode

An one-end-pumped Nd:YVO4 laser with fiber- coupled diode is designed. The mode matching between pump mode and laser mode is analyzed, and the optimum mode matching coefficient is obtained by optimizing the pump mode. Based on the optimal pump mode, a 14.2W TEM00 mode CW laser is obtained with a optical-optical efficiency of 55.7% at 1064 nm, with M2 factors of M2x = 1.16, M2y = 1.15. In Q-switching operation, 13.8W average power at a pulse repetition rate of 200 kHz is produced, with a stability of pulse peak value < 5%.
