Cr4+ ∶ YAG High Repetition Rate Passively Q-switched Nd ∶YVO4Laser Pumped by Laser Diode
The high repetition rate passively Q-switching of laser-diode end-pumped Nd∶YVO4 laser was realized by using Cr4+ ∶ YAG as saturable absorber. The pulse train with average output power of 1.21 W,repetition rate of 23.8 kHz,pulse width of 25 ns,pulse energy of 51 μJ and peak power of 2.03 kW was obtained with the absorbed pump power of 8.8 W. The dependence of pulse repetition rate,average output power,pulse width and single pulse energy on pump power and the transmission of output mirror was experimentally carried out. The experimental results showed that the pulse repetition rate and average output power decreased with pump power increasing when the pump power reached a certain extent. The experiment results were reasonably analyzed and discussed.
