| Abstract: | A high-repetition-rate eye-safe optical parametric oscillator(OPO)is experimentally demonstrated.The OPO is pumped by a passively Q-switched Nd∶GdVO4/Cr4+∶YAG laser and uses a non-critically phase-matched KTP as the OPO crystal.The conversion efficiency of the average power from input pump beam to 1.57μm output is 7% and the slope efficiency is up to 10.3%.At an incident pump power of 7.3W,the intracavity OPO system produces average powers at 1570 nm up to 0.48 W with a pulse width of 6ns and repetition rate of 15 kHz. |
