053 μm. The absorption spectrum of ammonia was presented to exhibit the feasibility in the created optical parametric oscillator system for spectroscopic measurements and fuel detection.
A mode-locked tunable dye laser continues to be created which can be synchronously pumped at superior repetition fees via the doubled output of the mode-locked Nd:YAG laser. The dye laser presents rigorous pulses of 35 psec length which can be greatly tunable, of around-remodel-confined bandwidth, and in time coincidence While using the pumping pulses.
Apart from the compactness and benign operating functions, it absolutely was the big adaptability in style and output features that led to the accomplishment of good-state lasers throughout the last 40 a long time.
By applying intracavity dispersion control, in the vicinity of-remodel-confined sign pulses of �?a hundred fs length with smooth single-peak spectrum are realized at 1264 nm, similar to an idler wavelength at 6440 nm. To the top of our understanding, This is certainly the first time this sort of practical idler powers from the deep-IR are created from the dispersion-compensated CSP femtosecond OPO at sub-one hundred MHz repetition fee.
We report new experimental benefits about the phase-matching properties of yellow coloration HgGa2S4 crystals for harmonic generation of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers within the 0.944-ten.5910 μm assortment. In addition, we current new Sellmeier equations that give a very good replica in the existing experimental outcomes as well as the released information factors for next-harmonic era of CO2 laser radiation at 9.
PA Ref-mobile, which significantly minimizes themeasurement problems on the methane focus in thecase of instability
Two parametric four-wave-mixing (FWM) processes in Rb atoms are researched making use of perturbation concept beneath the problem of rotating wave approximation. The two parametric FWM processes are coupled when they are thrilled coherently by a brief laser pulse that has a bandwidth encompassing the two corresponding upper Vitality amounts in The 2 FWM procedures.
A method is produced to solve the program of shortened equations describing parametric generation in a very one-frequency OPO cavity under nanosecond pulsed pumping. The frequency check here conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals plus the ideal reflection coefficient on the output mirror are estimated versus the pump Electricity density Wp at various values of the OPO nonstationarity .
Also, we executed a numerical simulation of chirped-pulse OPOs (CPOPOs) and disclosed which the spectral profile of your output from the CPOPO was suitable to both equally the parametric get profile with the nonlinear crystal as well as intra-cavity significant-buy dispersion.
Subject areas may be refined even more during the search results. The Topic aspect will reveal the significant-amount topics related to the content articles returned inside the search results. Distinctive COLLECTIONS
... The main knowledge on the refractive index of orange HGS posted by Levine et al. [35] bundled only handful of wavelengths inside the visible and around-IR equally as an indication with the feasibility of this crystal for birefringent period-matching. The refractive indices for your orange phase ended up calculated and tabulated between 0.
Quantum mechanical centered to start with basic principle calculations are utilized to get the unit mobile lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite framework for The very first time. For this, we treated HgGa2S4 in two differing kinds of web-site symmetries in the exact same Room group.
The selected nonlinear crystals show greater nonlinear conversion performance when compared with AgGaS two , with BaGa 2 GeS six Furthermore featuring a narrower angular spectrum of spontaneous parametric down conversion, beneficial in interferometric techniques. Our findings create a pathway for integrating State-of-the-art crystal technologies into mid-infrared metrology and imaging devices, setting the phase for potential developments in nonlinear interferometry and spectroscopy.
Diode-pumped optical parametric oscillation continues to be demonstrated for the first time to our information in only one Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions soak up the 812-nm radiation to crank out 1084-nm laser oscillation.
