Aculight Corp. (Bothell, WA) has announced the ArgosTM single-frequency, continuous-wave (CW) optical parametric oscillator (OPO) that provides multi-Watt, widely tunable, near- to mid-infrared output. Argos is a fiber-pumped, singly resonant OPO that provides continuous tuning from 1.4 to 2 microns and from 2.4 to 3.9 microns. It operates at room temperature and produces simultaneous output at two wavelengths, with available power between 1 and 5 Watts over the tuning range. The device offers 60 GHz mode-hop-free rapid tuning range. The OPO head measures 5" × 6" × 14" with a control unit of 10" × 19" × 19". Argos is suitable for applications in photoacoustic and cavity ringdown spectroscopy for trace gas detection.
