To describe intracavity frequency conversions in laser systems consisting of two laser cavi-ties combined with a nonlinear optical crystal, we analized rate equations and derived the out-put characteristics of the intracavity frequency conversion. From these results the existence of forbidden ranges in nonlinear coupling coefficients is discussed. For practical applications, effects due to a beam walk-off and an acceptance angle are taken into consideration.
