Narrow-band infrared picosecond pulses tunable between 1.2 and 1.4 microns generated by a traveling-wave dye laser
Abstract
A novel type of picosecond light source is the traveling-wave dye laser. It consists of a generator and an amplifier cell, both pumped by single pulses. Using the fast switching dye No. 5 with a fluorescence quantum efficiency of .0005, an energy conversion of the pump to the IR pulse of up to 10 percent is obtained. The spectral width of the IR pulses is 15 per cm over the tunability range of 1.18-1.4 microns. At 1.33 microns, Gaussian-shaped pulses of 4.4-ps duration are observed for pump pulses of 4.5 ps generated by a mode-locked Nd:glass laser. The output pulses show a high stability with a jitter of less than 0.2 ps.
