Optical parametric oscillator (OPO) is a light source that converts pump laser wave into two output waves. In optical gas analysis applications, the continuous wave (CW) laser light delivers high selectivity and precision. Ultraphotons OPO allows access to mid-infrared region (3-4 μm) and thus provides high sensitivity in optical trace gas detection. The technology allows outstanding tuning characteristics of the OPO and thus provides all relevant wavelengths for a wide range of applications.
