Kafka, J D; Baer, T M

An apparatus is described for producing a subpicosecond pulsewidth output from a dye laser at relatively high average power, comprising, a Nd:YAG pumping laser with means for generating a continuous wave mode-locked infrared laser beam, an infrared pulse compressor receiving the infrared beam and effective to narrow the pulsewidth of the beam, the pulse compressor compressing the infrared beam to a narrower pulsewidth, increasing peak power, to a pulsewidth at least as narrow as the relaxation time of an infrared dye of a dye laser to be pumped, frequency doubling means for doubling the frequency of the output of the infrared pulse compressor to produce a frequency doubled output in the green light range, and a synchronously pumped dye laser, positioned to be pumped by the frequency doubled green output, whereby a subpicosecond output may be obtained at high average power output through efficient pulse compression and frequency doubling of the pulse-compressed infrared beam.
