摘要：
A laser diode pumped Q-switched 935 nm Nd-doped Ca-3(NbGa)(2-x)Ga3O12 (Nd:CNGG) laser using a Cr, Nd:YAG crystal as a saturable absorber is demonstrated for the first time to our knowledge. An average output power of 74 mW for 935 nm Q-switched pulses and a repetition rate of 3.788 kHz are obtained. The pulse width is measured to be 26-33 ns under different pump powers. Some theoretical calculations are made to discuss the selective excitation of Nd3+ ion in the Nd:CNGG crystal. (C) 2009 Optical Society of America
