053 μm. The absorption spectrum of ammonia was introduced to demonstrate the feasibility in the designed optical parametric oscillator procedure for spectroscopic measurements and fuel detection.
Output idler energies about the microjoule stage are received with optimum conversion efficiency of eleven% for the amplifier phase, that's more than two moments much better than the effects attained by having an analogous sample from the extensively distribute materials AgGaS 2 .

By implementing intracavity dispersion Manage, close to-transform-constrained signal pulses of �?one hundred fs duration with smooth solitary-peak spectrum are attained at 1264 nm, corresponding to an idler wavelength at 6440 nm. To the top of our awareness, This is often The 1st time these functional idler powers within the deep-IR have already been produced from a dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition fee.
OPO have been improved by optimizing pump beam waistline and OPO cavity size. Both air-spaced and strong etalons were being tested to frequency
brought about oscillations during the idler wavelength of under 200MHz more than 300s; the short-expression balance was lower than 3MHz
Two parametric four-wave-mixing (FWM) procedures in Rb atoms are researched making use of perturbation concept underneath the affliction of rotating wave approximation. The two parametric FWM procedures are coupled when they're fired up coherently by a brief laser pulse having a bandwidth encompassing The 2 corresponding higher Vitality levels in the two FWM procedures.
air gap and energized in sequence by a common pump beam. The section from the interference is determined by the phase shifts at three frequencies.
Better-order nonlinear procedures in substitute resources will click here also be considered plus a dialogue on substance suitability for down-conversion of around-IR lasers in the mid-IR to satisfy many application requirements is likewise offered.
The 3rd harmonic of CO2-laser radiation has actually been received by passing the laser beam by two CdGeAs2 crystals in tandem, with the first crystal oriented for second-harmonic era and the next for sum mixing. Employing This method, we have accomplished an average exterior conversion effectiveness of one.
Normalization in the absorption signals within the PAD is completed based on the absorption indicators during the gasoline-stuffed
Quantum mechanical based to start with basic principle calculations happen to be used to get the unit mobile lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite framework for The very first time. For this, we dealt with HgGa2S4 in two differing kinds of web-site symmetries in the same Room group.
A pulsed TEA CO2 laser was employed to research the result of pump radiation parameters (method construction, wavelength, and pulse duration), concentrating conditions, absorption coefficient, and temperature around the efficiency of conversion into the second harmonic and on angular dependences of phase matching in ZnGeP2 crystals. Excellent settlement betweeen experimental and theoretical success is observed. Browse far more
