Laser characteristics of continuous-wave (cw) and passively Q-switched Nd : LGGG lasers based on the 4F3/2? 4I13/2transition of an neodymium ion are investigated. The lasing spectra of the cw and the Q-switching regimes are studied in detail. The thermal optical coefficient for the Nd : LGGG crystal at a wavelength of 1.33 ?m is estimated to be 15.3 × 10?6K?1. By inserting a quartz plate at the Brewster angle, the frequency of the Nd : LGGG laser is tuned. In the cw regime, the maximum output power at an incident pump power of 7.09 W is 802 mW and a slope efficiency is 13.2%. In the Q-switching regime, a minimum pulse duration of 9.75 ns is obtained with an output power of 176 mW and a repetition rate of 8 kHz. The maximum pulse energy and the highest peak power are 25.4 ?J and 2.4 kW, respectively.
