Generation of nearhyphen;infrared picosecond pulses by modehyphen;locked synchronous pumping of a jethyphen;stream dye laser

摘要

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