Generation of near-infrared picosecond pulses by mode-locked synchronous pumping of a jet-stream dye laser

Abstract
Picosecond pulses continuously tunable from 685 to over 900 nm have been obtained from a dye laser synchronously pumped by a mode‐locked krypton laser. The pulse duration was measured by autocorrelation techniques to be as short as 25 ps. Conversion efficiency up to 30% and average power in excess of 400 mW were observed. Continuous‐wave laser operation for three new dyes between 870 and 985 nm is also reported.
