Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variance-frequency generation in OPGaAs
The importance from the received benefits lies in the fact that to have the exact same conversion in SHG or DFM, just one now needs essential enter radiation with Considerably lessen intensity.

The concept of chemical transportation reactions (volatilization of a material through a low-unstable chemical intermediate at a temperature T1 and again-reaction with the mixture in a temperature T2, utilizing the temperature dependence in the chemical equilibrium associated) is a useful Software for expanding solitary crystals of numerous supplies which can't be simply acquired from the melt.
We report new experimental success about the phase-matching Attributes of yellow colour HgGa2S4 crystals for harmonic technology of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-ten.5910 μm variety. On top of that, we current new Sellmeier equations that give a excellent replica of your current experimental results and also the printed details points for second-harmonic era of CO2 laser radiation at 9.
The calculated Main amount binding energies are when compared with Those people of HgS, Fuel, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves being independent within the technological disorders of crystal growth. In distinction to the valence band spectrum, the distribution of electron states during the bandgap of HgGa2S4 crystals is discovered being strongly dependent on the technological ailments of crystal development as shown through the photoluminescence Investigation.

stabilize and tune the OPO, from which the stable etalon gave a better functionality. Temperature oscillations inside the PPLN crystal
... check here The initial details within the refractive index of orange HGS posted by Levine et al. [35] bundled only handful of wavelengths from the visible and close to-IR just as an illustration of your feasibility of this crystal for birefringent stage-matching. The refractive indices to the orange period were being measured and tabulated in between 0.
fuel analyzers is completed. The produced PA methane sensor is adapted for placement over the UAV’s board. Product
The chosen nonlinear crystals exhibit higher nonlinear conversion effectiveness in comparison to AgGaS two , with BaGa two GeS 6 In addition providing a narrower angular spectrum of spontaneous parametric down conversion, beneficial in interferometric techniques. Our findings establish a pathway for integrating Innovative crystal technologies into mid-infrared metrology and imaging programs, location the stage for future developments in nonlinear interferometry and spectroscopy.
This is actually the initially illustration of a broadband OPO functioning through the molecular fingerprint region, and we demonstrate its prospective by conducting broadband Fourier-rework spectroscopy applying water vapor as well as a polystyrene reference common.
