A spectrum of C2H2Π–2Σ+transition centered at 2928 cm−1has been measured in the gas phase using a high resolution difference‐frequency infrared laser spectrometer. The C2H molecules are produced in a hollow cathode discharge through a mixture of C2H2(∼20 mTorr) and H2(∼500 mTorr...
Improved performance of a continuous-wave (cw) laser spectrometer for Doppler-limited infrared spectroscopy of molecules based on difference-frequency generation (DFG) in AgGaS2 has been achieved. The spectrometer was configured to generate continuous scans of up to 1 cm−1 from 1550 to 2100 cm...
Photonics is a branch of technology concerned with the generation, control, and detection of photons, particularly in the visible and near-infrared spectrum. It encompasses applications ranging from fiber-optic communication to laser manufacturing. On the other hand, optics is the scientific study of...
High-resolution infrared identification of HOCS+ with difference frequency laser spectroscopydoi:10.1080/00268978700101161The v 1 fundamental band of HOCS+ has been observed in absorption in a hollow cathode discharge with a difference frequency laser system. The precise spectroscopic parameters have been...
Octave mid-infrared optical frequency comb from Er:fiber-laser-pumped aperiodically poled Mg: LiNbO 3 In this Letter, we report an octave-spanning mid-infrared (MIR) comb generation with a difference frequency generation (DFG) approach optimized for aperiodically poled Mg:LiNbO3 and nonlinear spectr...
