Abstract
A laser apparatus includes a master laser for emitting reference laser pulse light RPref having a wavelength of 914 nm and a pulse width of 0.5 ns; a microlens array for dividing the reference laser pulse light RPref into N pieces of light; optical fiber amplifiers - to -N being set to increase their length progressively in that order so as to have a propagation delay time of 0.5 ns, which is the pulse width of the divided pieces of reference laser pulse light DRPref to DRPrefN; a third harmonic generating unit for receiving the divided pieces of reference laser pulse light on which amplifying and delaying effects have been produced, and generating third harmonics TRD to TRDN having a wavelength of 305 nm and a pulse width of 0.5 ns; and an illuminating optical system for successively disposing the N third harmonics TRD to TRDN in parallel with each other, subjecting the N third harmonics TRD to TRDN to time multiplexing, and emitting the result.
