摘要：A frequency-doubled laser emitting at 555nm within a diode-side-pumped acousto optically Q-switched Nd:Gd3Ga5O12laser is demonstrated for the first time. A simple straight cavity scheme is employed to achieve a compact configuration and all the coatings are specially designed. A 25.5W 1110nm laser continuous wave output is achieved under the incident pump power of 168 W. A LiB3O5 crystal is used for second-harmonic generation of the laser. When the pump power is 168 W, the average output power at 555nm of 6.6W is obtained, corresponding to the optical conversion efficiency of 3.9%. The minimum pulse width (FWHM) is 176 ns with the pulse repetition rate of 10 kHz. The M2factors are measured to be 19.6 and 21.3 in the horizontal and vertical directions, respectively. © 2012 The Japan Society of Applied Physics.
