Abstract:
1. A system for generating a pulsed light output having a wavelength in the ultraviolet spectrum comprising: a tunable solid state laser for generating laser radiation; a solid state pump laser generating a pulsed output for pumping the tunable solid state laser; a seed laser generating laser radiation which is injected into the tunable solid state laser to lock the output of the tunable solid state laser to the wavelength of the laser radiation of the seed laser; and a harmonic generator including at least a second harmonic generating optic and a higher harmonic generating optic, wherein the harmonic generator converts the laser radiation from the tunable solid state laser into one of a fourth or fifth harmonic thereof and with the seed laser, pump laser and tunable solid state laser being configured so that the fourth or fifth harmonic output corresponds to a wavelength in the ultraviolet spectrum, said ultraviolet output being pulsed with a repetition rate of at least 5 kHz and having an average power of at least 2 mW.
