✦ Synopsis

We demonstrated an e cient and compact, diode-pumped passively Q-switched Nd:YVO4 laser operation at 1:064 m wavelength with high repetition rate, using Cr 4+ :YAG as saturable absorber, formed with a simple at-at resonator. The maximum CW output power of 4:05 W was obtained at the incident pump power of 8 W. For Q-switched operation, the maximum average output power was measured to be 1:4 W with the corresponding repetition rate of 200 kHz, the pulse width of 60 ns when the initial transmission of Cr 4+ :YAG crystal was 85%. The shortest pulse width of 12 ns, the largest pulse energy of 36 J and the highest peak power of 3 kW were obtained when the Cr 4+ :YAG crystal with an initial transmission of 60% was used.
