title: Continuous-wave tunable 8.7-microm spectroscopic source pumped by fiber-coupled communications lasers.
abstract: Tunable narrow-band cw difference-frequency generation at 8.7 microm was demonstrated in silver gallium selenide (AgGaSe(2)) at room temperature. The crystal was pumped by an injection-seeded Er/Yb-codoped fiber amplifier at 1.554 microm and a fiber-coupled diode-pumped monolithic ring Nd:YAG laser at 1.319 microm. The difference-frequency output was used for high-resolution spectroscopy of sulfur dioxide (SO(2)).
