title: Diode side-pumped 1.3414 microm Nd:YAP laser in Q-switched mode.
abstract: A diode side-pumped acousto-optic Q-switched Nd:YAP laser operating at 1.3414 microm has been reported. The stabilities of resonators and the influence of the temperature of cooling water on output power have been experimentally investigated. The average output powers and pulse widths with different couplers and repetition rates have also been measured and analyzed. Under the repetition rate of 5 kHz, a maximum average output power of 47.5 W was obtained with an optical-optical conversion efficiency of 8.6% and a slope efficiency of 20.2%. The peak power and the pulse width were 48.8 kW and 195 ns FWHM. The beam quality factors M(2) directed along the a and c axes were 22 and 28, respectively.
