Abstract
The results of a simple scheme to generate continuously tunable pulsed narr ow-bandwidth (less than 0.1 cm(-1)) light in the infrared are presented. A periodically poled lithium niobate (PPLN) optical parametric amplifier is s eeded with the filtered output of a PPLN optical parametric generator. A hi gh-finesse Fabry-Perot etalon is used as the filtering element, giving band widths as narrow as 0.08 cm(-1) and tunable over 18 cm(-1) without any adju stments to the PPLN crystals. High efficiency is obtained with a 15-ns 1-kH z Nd:YAG laser, giving energies of up to 180 mu J of signal at 1.6 mu m and 60 mu J of idler at 3.3 mu m. (C) 1998 Optical Society of America.
