Abstract
A (ZGP) optical parametric oscillator (OPO) with wide mid-IR tunability has been demonstrated. The singly resonant angle-tuned ZGP OPO was pumped by 100-ns erbium laser pulses at and yielded output that was continuously tunable from 3.8 to (type I phase matching) and from 4 to (type II phase matching). An OPO pump threshold was less than 1 mJ in the whole range of the output, and the quantum conversion efficiency reached 35%. An OPO linewidth was typically a few wave numbers; however, with a single intracavity etalon (uncoated Si plate) in a type II OPO it was narrowed to . We demonstrate the sensitive detection of gas with the narrow-linewidth OPO.
