Abstract
A stable pulse-burst GdVO4/Nd:GdVO4 laser oscillator with repetition rate up to 500kHz is demonstrated by use of a pulsed diode-laser of Stabilized Wavelength 879nm as the pump source. While the pulsed 879nm LD was operated at the repetition rate of 100Hz and the pump duration was 1ms, the different output characteristics of pulse-burst GdVO4/Nd:GdVO4 laser were obtained by adjusting the repetition rate of A-O Q-switch. When the total pump energy was 120mJ, the pulse number of 100, 200 and 500, the burst energy of 25mJ, 35mJ and 40mJ, the pulse width of 8.5ns, 12ns and 27ns were achieved at repetition rate of 100kHz, 200kHz and 500kHz, respectively. The relative single pulse energies were reached to 250μJ at 100kHz, 175μJ at 200kHz and 80μJ at 500kHz. The peak powers were reached to 29.4kW at 100kHz, 14.6kW at 200kHz and 3.0kW at 500kHz. The M2 factor was measure to 1.4.
