Inexpensive, pulsed, tunable ir dye laser pumped by a flashlamp-driven dye laser.
A flashlamp-driven dye laser with a 250-ns, 10-mrad divergence, 2-mm-diam beam at 620 nm is used to pump an ir dye laser. The ir laser pulses are tunable from 700 to 900 nm with spectral widths of less than 1 A. Peak ir powers of 100 W have been obtained with a 5-k W pump power.
