Paper Abstract

In common intra-cavity SHG schemes, the requirement for high(st) level of fundamental frequency power inside the non-linear crystal contradicts with the condition for extracting the maximum power available from the laser active medium. This impedance mismatch problem is removed by using the fundamental frequency power enhancement in two steps, the first one being optimized for maximum power outcoupling while at the second step the circulating inside nonlinear crystal power is further increased for maximum efficiency of SHG process. Experimentally proved this approach allows 3-5 times higher SH output power from DPSS lasers at given pump as compared with traditional schemes.
