Abstract

Nd3+∶Ca4GdO(BO3)3, known as Nd∶GdCOB, is a new self-frequency doubling laser crystal. Using Cr 4+∶YAG as passive Q-switch, the Q-switched laser running at 0.53 μm with the Nd∶GdCOB crystal is realized. The pulse width, single pulse energy and repetition rate under different small-signal transmission of Cr 4+∶YAG and different pump conditions are measured and the numerical solutions of the coupling wave rate equations agree with the experimental results.
