Optical parametric oscillator pumped at ~one µm with intracavity mid-IR change-frequency generation in OPGaAs
We report on the femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) dependant on the Kerr-lens-method-locked Ti:sapphire laser because the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO based upon the nonlinear crystal, CdSiP two , synchronously pumped inner to some MgO:PPLN femtosecond OPO, We've produced broadly tunable radiation across 5958�?117 nm working with fast static cavity hold off tuning, which has a most electrical power of sixty four μW at 6791 nm, constrained by the absorption in mirror substrates and polarization-dependent intracavity losses.

In each the circumstances received device cell parameters are similar, which shows the accuracy of present tactic. The electronic band structures display the semiconducting actions in each the cases. The density of states plot may also be studied and talked about.
We report new experimental benefits to the period-matching Homes of yellow shade HgGa2S4 crystals for harmonic era of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers from the 0.944-10.5910 μm range. Moreover, we present new Sellmeier equations that give a excellent replica with the existing experimental outcomes together with the printed info details for 2nd-harmonic generation of CO2 laser radiation at nine.
PA Ref-mobile, which considerably cuts down themeasurement mistakes from the methane concentration in thecase of instability

air hole and thrilled in sequence by a common pump beam. The section on the interference relies on the section shifts at a few frequencies.
The particular heat and thermal conductivity of HgGa2S4 are calculated. It's concluded more info which the merged Houses of HgGa2S4 crystals can offer for them a leading situation One of the resources used in nonlinear-optical units for mid-IR-frequency conversion.
The technology of rising mercury thiogallate crystals (HgGa2S4) is improved and substantial-top quality bulk samples are created. The basic optical and thermal Qualities of such crystals are studied. The transmission spectra of mercury thiogallate are measured and its nonlinear properties such as the quadratic susceptibility, tuning curves, along with the optical-injury resistance may also be decided.
... The initial knowledge within the refractive index of orange HGS printed by Levine et al. [35] integrated only couple wavelengths while in the visible and close to-IR equally as an indication of your feasibility of the crystal for birefringent phase-matching. The refractive indices for that orange stage had been measured and tabulated concerning 0.
twelve μm and explain all frequency conversion techniques realized to date with them in addition to upcoming possible applications. Keywords and phrases: Ternary and quaternary semiconductors, defect chalcopyrites, good methods, nonlinear optical crystals, mid-infrared
One-phase sub-two hundred fs mid-infrared technology from an optical parametric oscillator synchronously pumped by an erbium fiber laser
Diode-pumped optical parametric oscillation is shown for the first time to our know-how 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 in the 812-nm radiation to create 1084-nm laser oscillation.
