Abstract:

The design of a flashlamp-pumped dye laser capable of emitting light pulses 500 ns wide FWHM with a risetime of 300 ns is presented. The energy output in the visible region of light is 1 to 10mJ with an energy conversion efficiency of about 0.01 at a repetition rate of 30 pps. The design of an acousto-optic modulator used to mode-lock the dye laser by intracavity loss modulation is presented. The laser output for a given cavity length depends on the frequency and voltage applied to the modulator a 10 - 100 modulated output can be obtained with 1 V rms - 20 V rms, whereas train of light pulses narrower than 0.8 ns FWHM can be obtained with 80 V rms.
