In conclusion, we classified the single-crystal upconversion OPO's with siinultaneous SFG

and investigated their plane-wave dynamics. Our results show that classes A and D are efficient frequency upconverters. The performance of class A OPO's is limited by crystal properties whereas classes C and D can be optimized by adjusting the polarization rotation angle.
