Abstract :
Diode-pumped passively Q-switched solid-state laser with extremely short high-peak-power pulses are of potential interest for numerous applications. In this paper we present a resonator that is formed by a coated c-cut Nd:GdVO4 or Nd:YVO4 crystal and a coated Cr4+:YAG crystal. The studies of the present performance indicate that c-cut Nd:GdVO4 and Nd:YVO4 crystal are very convenient material for short pulse (sub-nanosecond) and high-peak power lasers. It is demonstrated that at 2 W pump power, 17.8 nJ pulses of 0.85 ns duration at a pulse repetition rate of 13 kHz can be generated in the c-cut Nd:GdVO4 and 18 nJ pulses of 0.85 ns duration at a pulse repetition rate of 13.5 kHz at 2.4 W pump power in the c-cut Nd:YVO4.
