Abstract :
Summary form only given. We previously reported a high-conversion-efficiency, tandem KTA-CdSe OPO source capable of covering four bands in the spectral range from 1.5 to 10 /spl mu/m. The design uses the angle-tuned, idler output of a KTA OPO to pump a non-critically phase-matched (NCPM) CdSe OPO. We use two techniques to increase the KTA OPO efficiency (1) difference-frequency generation (DFG) in a second KTA crystal placed in the KTA OPO cavity, and (2) injection-seeding of single frequency radiation at the signal wavelength into the KTA OPO cavity. We also demonstrate a tandem OPO pumped by a CW-diode-pumped, Q-switched, 4-kHz-repetition-rate, Nd:YLF laser.
