摘要：

We describe a method that overcomes the observed saturation effect appearing in cross polarized wave (XPW) generation. The previously reported internal efficiencies for XPW generation are known to be limited to around 15% whatever the length of the nonlinear medium and/or the input intensity values are. At the opposite, the theoretical limit had been estimated to be close to 25%. Here we show that the saturation level of XPW generation efficiency can be drastically shifted up by using two thin nonlinear crystals put at a given distance one to the other. An internal efficiency of 30% is demonstrated experimentally using two BaF2 crystals. (c) 2006 Optical Society of America
