Abstract
A pulse amplified cw dye laser has been developed which produces a peak power of 50 to 100 kilowatts with a bandwidth of about 80 MHz. Frequency doubling this output produces power levels of up to 1 kilowatt, sufficient for observing two-photon processes in noble gases. Doppler-cancelled two-photon resonant, three-photon ionization spectra of several states of xenon and one state of krypton have been recorded which clearly show hyperfine splittings in odd isotopes. State assignments and fitted hyperfine constants have been determined where appropriate.© (1981) COPYRIGHT SPIE--The International Society for Optical Engineering.
