摘要
Abstract
An optical parameter oscillator (OPO) based on a Nd: YAG laser and two pieces of KTiOPO4 (KTP) nonlinear crystal that could be tuned from 750-800 nm was built for alkali vapor lasers' high-intensity pumping experiment. It can provide 113 mJ each pulse at the central wavelength of 780. 2 nm with a duration of 15. 43 ns. This means the peak power could be as high as 7 MW. The spectral line width is about 0. 38 nm and the beam diameter is 5. 5 mm. Clear fluorescence can be observed when the signal light passes through the 10 cm long Rb cell with Ar buffer gas at a temperature of 120 ℃, which demonstrates the validity of this OPO system to be used in alkali laser studies.关键词
