053 μm. The absorption spectrum of ammonia was presented to display the feasibility on the formulated optical parametric oscillator technique for spectroscopic measurements and gasoline detection.
The significance of the attained final results lies in The truth that to obtain the exact conversion in SHG or DFM, just one now necessitates basic enter radiation with A lot decreased intensity.
Aside from the compactness and benign working capabilities, it was the big versatility in structure and output features that led to the results of strong-state lasers during the last 40 years.
By implementing intracavity dispersion control, in close proximity to-renovate-restricted sign pulses of �?one hundred fs length with smooth one-peak spectrum are obtained at 1264 nm, equivalent to an idler wavelength at 6440 nm. To the most beneficial of our understanding, That is The very first time these useful idler powers inside the deep-IR happen to be created from a dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition price.
We report new experimental final results over the stage-matching Qualities of yellow coloration HgGa2S4 crystals for harmonic era of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers from the 0.944-ten.5910 μm selection. In addition, we present new Sellmeier equations that give a great copy of your current experimental success and also the posted data factors for next-harmonic era of CO2 laser radiation at nine.
The substantial conversion performance and big selection of radiation wavelength tuning allows to expect this substance could contend with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Despite the substantial difficulty of massive dimensions crystals progress procedure.
Two parametric 4-wave-mixing (FWM) procedures in Rb atoms are examined working with perturbation principle under the problem of rotating wave approximation. The 2 parametric FWM procedures are coupled when they are enthusiastic coherently by a short laser pulse by using a bandwidth encompassing the two corresponding upper Power degrees in The 2 FWM procedures.
Based on the theories of period matching and satisfactory composition ratio, the impact of composition ratio on the frequency more info conversions of two types (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In thought of corresponding sellmeier equations, section matching diagrams of second harmonic generation and optical parametric oscillations pumped by the popular Nd3+:YAG and Ho3+:YLF lasers had been calculated, in addition to satisfactory composition ratios with numerous compositions.
Additionally, we carried out a numerical simulation of chirped-pulse OPOs (CPOPOs) and disclosed that the spectral profile with the output from a CPOPO was suitable to both of those the parametric achieve profile of the nonlinear crystal plus the intra-cavity substantial-get dispersion.

... The very first information about the refractive index of orange HGS released by Levine et al. [35] bundled only couple of wavelengths during the seen and in close proximity to-IR just as an indication on the feasibility of this crystal for birefringent period-matching. The refractive indices with the orange phase had been measured and tabulated among 0.
Quantum mechanical based mostly initially principle calculations have already been used to acquire the device cell lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite construction for The very first time. For this, we addressed HgGa2S4 in two differing kinds of site symmetries in exactly the same space group.
Recent mid-IR NLO crystals could be divided into four classes, i.e., classical binary and ternary metallic pnictides and chalcogenides, quaternary metallic chalcogenides, binary and ternary metallic halides, and various-bond-sort hybrid compounds that contain not less than two forms of clearly unique chemical bonds during the crystal structures. Metallic pnictides and chalcogenides have got Considerably consideration on developing huge crystals. Distinctive-bond-kind hybrid is a completely new household of mid-IR NLO elements, and several of them ended up located in the last ten years. In steel halide program, equally progress in growing big crystals and exploring new types are actually designed.
Diode-pumped optical parametric oscillation has become shown for The very first time to our information in an individual Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions take up the 812-nm radiation to deliver 1084-nm laser oscillation.
