Both KTP( KTi0PO4)"' and BBO( -BaB204)"' have striking features used for OPO: large nonlinear coefficients, high optical damage threshold, good chemical and physical properties and easily to be polished. In our experiment the output of BBO optical parametric oscillator (OPO) was obtained over the range of 0.33-1.73 Ã‚Âµ m. The maximum energy conversion efficiency of BBO OPO is 11% and maximum output energy is 10mj/putse. The tuning range of KTP OPO covers from 0.76 to 1.78Ã‚Âµm. The maximum conversion efficiency of KTP OPO is 20% and the maximum output energy is 20mj/pulse.
