.. [Clearly show entire abstract] parametric oscillator. The 2 independently focused beams were produced to overlap In the crystal. The concentrating parameters of The 2 beams were being concerning the exact same. The concentrating function produced by Boyd and Kleinman for tightly centered beams was extended to periodically poled crystals to be able to suit the temperature-tuning curve. A 0.sixty six%/W effectiveness was received for the main difference frequency mixing system.

Output idler energies around the microjoule degree are obtained with greatest conversion effectiveness of 11% for your amplifier phase, which happens to be much more than two occasions much better than the outcome received using an analogous sample from the greatly unfold product AgGaS 2 .

crystals with ultrafast Yb-ion laser pump is proposed. The final results variety a valuable reference for the choice of resources

The thought of chemical transportation reactions (volatilization of a fabric through a small-risky chemical intermediate in a temperature T1 and back-response of your combination at a temperature T2, utilizing the temperature dependence of the chemical equilibrium involved) is really a valuable Instrument for escalating solitary crystals of numerous elements which can not be effortlessly acquired from your melt.

from the laser emission wavelength. The minimal measured history sign on the PA sensor (employing substantial purity

The measured Main amount binding energies are when compared with Individuals of HgS, GaS, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves being unbiased over the technological circumstances of crystal expansion. In distinction to the valence band spectrum, the distribution of electron states while in the bandgap of HgGa2S4 crystals is uncovered being strongly dependent upon the technological conditions of crystal development as demonstrated through the photoluminescence Evaluation.

Two parametric 4-wave-mixing (FWM) processes in Rb atoms are studied applying perturbation concept beneath the situation of rotating wave approximation. The two parametric FWM procedures are coupled when they are enthusiastic coherently by a short laser pulse which more info has a bandwidth encompassing the two corresponding upper energy amounts in the two FWM processes.

We existing a numerical study for the design of economical MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of leading-hat transverse intensity profile, plus a double-pass pump cavity configuration. Specifically, we examine the result of domain condition within the conversion performance. We thought of two varieties of domain constructions: "ideal vertical-wall" and "wedge-shaped" domains and our numerical effects exhibit that at higher pump pulse energies, the conversion efficiency saturates, and the saturated effectiveness is almost unbiased on the domain shapes.

... The initial details to the refractive index of orange HGS printed by Levine et al. [35] involved only handful of wavelengths during the obvious and around-IR equally as an illustration from the feasibility of the crystal for birefringent stage-matching. The refractive indices for the orange phase were being calculated and tabulated between 0.

12 μm and describe all frequency conversion strategies understood up to now with them together with future prospective apps. Keywords: Ternary and quaternary semiconductors, defect chalcopyrites, sound remedies, nonlinear optical crystals, mid-infrared

Latest mid-IR NLO crystals is usually divided into four groups, i.e., classical binary and ternary metal pnictides and chalcogenides, quaternary steel chalcogenides, binary and ternary metallic halides, and distinct-bond-type hybrid compounds that comprise at the least two types of certainly distinctive chemical bonds within the crystal constructions. Metallic pnictides and chalcogenides have got Considerably notice on expanding massive crystals. Unique-bond-type hybrid is a fresh relatives of mid-IR NLO materials, and lots of of them have been present in the final ten years. In metallic halide system, each progress in developing significant crystals and exploring new types are already made.

three% rms more than 12 h in great beam excellent. The close to-IR signal pulses through the OPO Have a very Gaussian pulse duration of �?19 ps , calculated at 1284 nm. We've investigated the temperature tuning traits in the OPO and in comparison the data With all the theoretical calculations applying The latest Sellmeier equations and thermo-optic coefficients with the crystal. To the best of our awareness, this is the to start with picosecond OPO based on CSP working at MHz repetition fees.
