053 μm. The absorption spectrum of ammonia was offered to show the feasibility of your formulated optical parametric oscillator system for spectroscopic measurements and gasoline detection.
Effects of thermal conductivity measurements are described for several of the more lately developed nonlinear optical crystals. New or considerably revised values of thermal conductivity have been acquired in six materials. Notable thermal conductivities measured ended up All those for AgGaS2 [0.014 W/(cm K) and 0.
The primary-rules density functional calculations are executed to study the geometries and electronic buildings of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite structures, and the optical properties of all crystals are investigated systematically. The results reveal that these compounds have identical band structures along with the band hole decreases from S to Se to Te. With the linear optical Houses, a few crystals present very good light-weight transmission inside the IR and section visible locations, and particularly, HgGa2S4 and HgGa2Se4 crystals have reasonable birefringence.
By applying intracavity dispersion Management, in close proximity to-rework-restricted sign pulses of �?one hundred fs duration with sleek single-peak spectrum are obtained at 1264 nm, equivalent to an idler wavelength at 6440 nm. To the very best of our awareness, That is The very first time these realistic idler powers during the deep-IR have been produced from a dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition fee.
We report new experimental benefits on the period-matching Qualities of yellow colour HgGa2S4 crystals for harmonic technology of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers from the 0.944-10.5910 μm variety. In addition, we current new Sellmeier equations that provide a fantastic copy from the existing experimental benefits plus the released data factors for next-harmonic generation of CO2 laser radiation at 9.
During this Introduction We'll provide a shorter overview on the crucial milestones in the development of stable-state lasers, focus on the choice of effectiveness parameters achievable Using these lasers, and point out important programs.
Optical properties of orange phased HgGa2S4 crystal is investigated. Technology of tunable middle infrared radiation by next harmonic of tunable CO2 laser radiation has actually been demonstrated. Next harmonic conversion efficiency with regard to other infrared crystal has also been discussed.
We existing a numerical research for the look of productive MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of major-hat transverse intensity profile, plus a double-go pump cavity configuration. In particular, we investigate the impact of domain form about the conversion performance. We considered two varieties of domain constructions: "ideal vertical-wall" and "wedge-formed" domains and our numerical effects show that at higher pump pulse energies, the conversion efficiency saturates, along with the saturated effectiveness is nearly impartial in the domain shapes.
The precise heat and thermal conductivity of HgGa2S4 are measured. It really is concluded which the put together Houses of HgGa2S4 crystals can offer for them a leading situation Among the many elements Utilized in nonlinear-optical gadgets for mid-IR-frequency conversion.
Matters may be refined further more inside the search engine results. The Topic aspect will expose the higher-stage topics connected to the content articles returned during the search results. Specific COLLECTIONS
Simple method for decreasing the depolarization loss ensuing from thermally induced birefringence in reliable-point out lasers
Quantum mechanical dependent initially principle calculations are utilized to obtain the unit mobile lattice parameters of mercury click here thiogallate (HgGa2S4) in defect stannite composition for the first time. For this, we treated HgGa2S4 in two different types of web site symmetries in a similar Place team.
On this paper we theoretically look into one of the most successful pump temporal condition for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Assessment consists of fixing the best Command trouble utilizing the amount equation formalism. The OPO best buildup habits is derived for almost any OPO configuration, and we demonstrate that the optimal pump pulse shape is a double rectangle. The first rectangle is optimized with the buildup course of action, even though the second 1 is optimized for the continual condition, and both rely in a different way on the OPO mirror reflectivities and also the offered pump energy and utmost peak energy.
