| Abstract: | Amplified spontaneous emission of a dye cell is parametrically amplified in barium betaborate (BBO) crystals. Pumping the system by the third harmonic of a Nd:YAG laser a tuning range from 3500 to 25080 cm–1 is accessible with energy conversion efficiencies of several percent. Properties of ultrashort light pulses in the visible and UV spectral range are presented. A spectral width of 10 cm–1 and a pulse duration of approximately 20 ps are measured. |
