Continuous wave optical parametric oscillator for quartz-enhanced photoacoustic trace gas sensing

  • Published 2007


A continuous wave optical parametric oscillator, generating up to 300 mW idler output in the 3–4 μm wavelength region, and pumped by a fiber-amplified DBR diode laser is used for trace gas detection by means of quartz-enhanced photoacoustic spectroscopy (QEPAS). Mode-hop-free tuning of the OPO output over 5.2 cm−1 and continuous spectral coverage exceeding… (More)
