Laser apparatus including two different, pulsed MOPAs, one having a fundamental wavelength of 1064 nm and the other having a fundamental wavelength of 1547 nm, provide trains of optical pulses. The 1064-nm pulses are frequency-quadrupled to a wavelength of 266 nm. The 1547-nm pulses are first mixed with the 266-nm pulses to provide pulses having a wavelength of 227 nm. The 227-nm pulses are then mixed with residual 1547-nm pulses from the first mixing to provide 198-nm output pulses of the apparatus.
