.. [Show entire summary] parametric oscillator. The 2 independently concentrated beams have been designed to overlap Within the crystal. The concentrating parameters of The 2 beams were being regarding the exact same. The focusing perform made by Boyd and Kleinman for tightly concentrated beams was extended to periodically poled crystals as a way to in good shape the temperature-tuning curve. A 0.66%/W effectiveness was received for the real difference frequency mixing procedure.
We report with a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) based on the Kerr-lens-mode-locked Ti:sapphire laser since the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO depending on the nonlinear crystal, CdSiP two , synchronously pumped inside to some MgO:PPLN femtosecond OPO, we have generated broadly tunable radiation across 5958�?117 nm employing immediate static cavity hold off tuning, having a greatest electrical power of sixty four μW at 6791 nm, limited from the absorption in mirror substrates together with polarization-dependent intracavity losses.
Aside from the compactness and benign functioning functions, it absolutely was the big overall flexibility in layout and output characteristics that led on the success of solid-condition lasers over the last forty decades.
By utilizing intracavity dispersion Handle, close to-renovate-constrained sign pulses of �?one hundred fs duration with clean single-peak spectrum are obtained at 1264 nm, akin to an idler wavelength at 6440 nm. To the most effective of our understanding, This is often The very first time such functional idler powers in the deep-IR have already been produced from the dispersion-compensated CSP femtosecond OPO at sub-100 MHz repetition charge.
We report new experimental outcomes over the stage-matching Homes of yellow coloration HgGa2S4 crystals for harmonic era of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers while in the 0.944-10.5910 μm vary. On top of that, we present new Sellmeier equations that supply a excellent copy of the existing experimental effects and also the released information factors for 2nd-harmonic technology of CO2 laser here radiation at 9.
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Like sign and idler, it could be consistently tuned from 1.261 by way of two.532 μm by varying the pump wavelength. Two big enhancements were being accomplished, such as the relationship from the sign and idler tuning ranges as well as high output pulse Strength in the signal and idler tuning ... [Present whole summary] ranges. The very first enhancement was realized by discovering two certain sets of section-matching angles. The 2nd advancement was understood by making use of 5 sets of resonator mirrors for oscillating either sign or idler.
Though applying an institutional account for this website we don’t observe any particular, general performance, useful or 1st or 3rd occasion connected info.
Pumping mid-IR optical parametric oscillators in close proximity to one μm is attractive for its simplicity and power scaling functionality. To this intention, large bandgap non-oxide nonlinear crystals are required.
Modeling and experimental analyze on phase matching of next harmonic generation in different shade Hg Ga two S 4 crystals are carried out. Utilizing the acknowledged Sellmeier equations, the dispersion relation with weighting proportionally to short-wavelength boundary on the crystal transparency band is proposed.
Assessment of new, promising large-band-gap nonlinear crystals for your mid-IR is specified. We focused on ternary and quaternary chalcogenides and centered on their Bodily and chemical properties, which Together with linear and nonlinear optical Attributes, figure out the effectiveness of crystal utilization in certain laser experiments. The correlation among the composition, framework and output parameters and also the trends in adjustments of the leading characteristics including band gap, nonlinear susceptibility, laser problems threshold, and many others, are demonstrated.
... The 1st information to the refractive index of orange HGS published by Levine et al. [35] incorporated only couple wavelengths within the obvious and close to-IR equally as an indication in the feasibility of the crystal for birefringent section-matching. The refractive indices for the orange stage ended up calculated and tabulated between 0.

In this particular paper we theoretically look into essentially the most efficient pump temporal condition for pulsed operation of optical parametric oscillators (OPOs). The theoretical Evaluation contains fixing the optimum control challenge using the amount equation formalism. The OPO exceptional buildup behavior is derived for any OPO configuration, and we demonstrate that the optimum pump pulse condition can be a double rectangle. The very first rectangle is optimized for that buildup procedure, though the second just one is optimized for that continuous condition, and both of those depend otherwise around the OPO mirror reflectivities together with the accessible pump Electricity and maximum peak electricity.
