Abstract
The stimulated emission of new infrared dyes was investigated. The dyes have shortS 1-lifetimes between 5 and 12 ps with corresponding low fluorescence quantum efficiencies of 10−3 to 10−4. In spite of this, 2% of the pumping energy were converted to an intense infrared pulse with frequencies between 5550 cm−1 (1.8 μm) and 7150 cm−1 (1.4 μm). The dye solutions were excited by single picosecond pulses of a Nd:glass laser in a travelling wave system consisting of a diffraction grating and a tranversely pumped dye cell. The pulse duration at 6250 cm−1 was measured to be 6 ps.
