Paper Abstract

We report a high-power diode-double-end-pumped Q-switched Nd:YVO4 red laser through intracavity frequency-doubling with a type-I critical phase-matched LBO crystal. At the repetition frequency of 26 kHz, the maximum quasi-continuous-wave (QCW) output power at 671 nm was measured to be 9.2 W at the incident pump power of 62.4 W with the corresponding optical conversion efficiency of 14.7%; the pulse width of about 106 ns; the pulse energy of 353.8μJ; the peak power of 3.34 kW, respectively. The perfect performance indicated that the double-end-pumped technique could effectively diminish the thermal lens effect, extend the range of the stable resonator region and achieve a high optical conversion efficiency to obtain a high output power.
