A new intracavity frequency-tripled laser resonator design that circumvents the birefringence interference problems normally associated with a laser resonator with two intracavity nonlinear crystals is developed. Two hundred mW of UV laser output in a TEM(00) mode is obtained from an intracavity frequency-tripled Nd:YAG laser; the 250-Hz pulsed input does not exceed 400 W. LBO and BBO nonlinear crystals are utilized for second-harmonic generation and third-harmonic generation, respectively. The peak power of the UV output measures 90 kW.
