Generation of efficient subnanosecond self-stimulated Raman pulses by a diode-pumped passively Q -switched Nd:YVO 4/Cr 4+:YAG laser is demonstrated. Experimental results reveal that self-frequency Raman conversion can be achieved with a c -cut Nd:YVO 4 crystal in a nearly hemispherical cavity. At 2.0 W of incident pump power, the self-stimulated Raman laser produces stable 710-ps pulses at a Stokes wavelength of 1178.6 nm with 7.2µJ of pulse energy at a 17-kHz repetition rate.
