Nd3+:Ca4GdO(BO3)3, known as Nd:GdCOB, is a new self-frequency doubling laser crystal. Using Cr4+:YAG as passive Q-switch, we have realized the Q-switched laser running at 0.53 μm with an Nd:GdCOB crystal. Meanwhile, the pulse width, the single pulse energy and the repetition rate under different small-signal transmission of Cr4+:YAG and different pump conditions are measured and the numerical solutions of the coupling wave rate equations agree with the experimental results.
