Abstract:
A system for generating a pulsed light output having a wavelength on the order of 193 nm comprising:a Ti:Sapphire laser for generating laser radiation; a solid state pump laser generating a pulsed output for pumping the Ti:Sapphire laser; a seed laser generating laser radiation which is injected into the Ti:Sapphire laser to lock the output of the Ti:Sapphire 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 fourth harmonic generating optic, wherein the harmonic generator converts the laser radiation from the Ti:Sapphire laser into the fourth harmonic thereof and with the seed laser, pump laser and Ti:Sapphire laser being configured so that the fourth harmonic output corresponds to a wavelength of about 193 nm, said fourth harmonic output being pulsed with a repetition rate of at least 5 kHz and having an average power of at least 2 mW.
