Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variation-frequency era in OPGaAs
Output idler energies to the microjoule degree are received with maximum conversion efficiency of 11% with the amplifier stage, that is greater than two instances better than the results acquired using an analogous sample on the greatly spread material AgGaS 2 .

The concept of chemical transport reactions (volatilization of a fabric through a very low-unstable chemical intermediate at a temperature T1 and back again-reaction of the combination at a temperature T2, using the temperature dependence of your chemical equilibrium associated) can be a precious Software for increasing one crystals of many elements which cannot be quickly attained from your soften.
Self-referenced octave-wide subharmonic Hole optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
PA Ref-mobile, which appreciably minimizes themeasurement errors on the methane concentration in thecase of instability

Vibrational spectra of Li-made up of nonlinear crystals as well as their software in THz radiation technology are talked about. Employing an illustration of LiGaS2, the defect impact on spectroscopic qualities is shown. Large-temperature annealing in a suitable ambiance enables a single to get rid of prolonged and issue defects and to Enhance the transparency. Power construction and parameters of most important place defects like anion vacancy (File-Centre) and cation antisite defect GaLi calculated from the very first ideas agree well While using the experimental results.
The 3rd harmonic of CO2-laser radiation has actually been attained by passing the laser beam by two CdGeAs2 crystals in tandem, with the main crystal oriented for next-harmonic era and the second for sum mixing. Making use of this technique, We've accomplished an average exterior conversion performance of 1.
Uncomplicated method for decreasing the depolarization decline ensuing from thermally induced birefringence in stable-condition lasers
for the detection of molecular trace gasses. The oscillation threshold, output electrical power and security of The only resonant
The selected nonlinear crystals show higher nonlinear conversion effectiveness when compared with AgGaS two , with BaGa 2 GeS six In addition featuring a narrower angular spectrum of spontaneous parametric down conversion, advantageous in interferometric techniques. Our findings create a pathway for integrating advanced crystal technologies into mid-infrared metrology and imaging units, environment the phase for future developments in nonlinear interferometry and spectroscopy.
Change frequency mixing of strongly concentrated Gaussian beams in periodically poled LiNbO3 was investigated. The beams were being concentrated In website the crystal without the need of destruction. Mixing of cw and pulsed laser units was used to reduce the thermal lensing results inside this crystal. A small-ability cw one.064‐μm Nd:YAG laser beam was applied as the pump, Whilst the sign beam came from a picosecond optical .
