Abstract
An optical parameter oscillator base on KTP nonlinear optical crystals and a frequency doubling Nd:YAG lase was built. The wavelength of the signal light could be tuned from 750-800nm. At the wavelength of 780.2nm it could provide 62mJ each pulse with duration of 14 ns and spectrum (FWHM) about 0.4nm, and at the wavelength of 755nm the energy of each pulse was 10mJ with duration of 8ns. When the signal passed through a 10cm long Rb cell with Ar buffer gas at the temperature of 120°C and the wavelength was tuned from 779nm to 781nm, it could be observed that the fluorescence in the cell changed from dim to clear at first and then declined. Fluorescence could also be observed when the signal wavelength was 755nm and the cell was heated to 180℃. Which indicated that this OPO can provides over 1MW peak power for the research of rubidium lasers and rubidium-rare gas excimer lasers.
