Diode-pumped continuous-wavelength and passively Q-switched laser with a novel Nd:CTGS crystal were reported. In continuous-wave operation, maximum output power of 3.5 W was obtained with slope efficiency of 38.6%. With Cr4+:YAG as the saturable absorber, passively Q-switched 1065 nm laser with high power and high energy were demonstrated. Maximum output power was 1.6 W with slope efficiency of 21.2%. Minimum pulse width of 8.4 ns was obtained with pulse repetition rate of 33.1 kHz, corresponding to maximum pulse energy of 45.7 μJ and peak power of 5.4 kW.
