Claim:
1. A laser for generating light, the laser comprising: a pump laser configured to generate a pump frequency having a corresponding wavelength of between approximately 1105 nm and approximately 1130 nm; a fundamental laser configured to generate a fundamental frequency from a portion of the pump frequency, the fundamental frequency having a corresponding wavelength of between approximately 1150 nm and approximately 1175 nm; a fifth harmonic generator module configured to generate a fifth harmonic of the fundamental frequency; and a frequency mixing module configured to combine the pump frequency and the fifth harmonic frequency to generate an output wavelength between approximately 189 nm and approximately 200 nm, wherein the frequency mixing module further comprises an optical cavity configured to recirculate an unconsumed portion of the pump frequency.
