.. [Show complete abstract] parametric oscillator. The two independently focused beams were being built to overlap Within the crystal. The focusing parameters of the two beams have been with regard to the same. The focusing function produced by Boyd and Kleinman for tightly centered beams was extended to periodically poled crystals to be able to match the temperature-tuning curve. A 0.sixty six%/W performance was acquired for the difference frequency mixing process.

The significance of your obtained outcomes lies in the fact that to find the very same conversion in SHG or DFM, one particular now involves basic enter radiation with Substantially reduced intensity.

crystals with ultrafast Yb-ion laser pump is proposed. The outcome kind a valuable reference for the selection of components

A straightforward procedure for lessening the decline that is because of depolarization resulting from thermally induced strain birefringence in strong-state lasers is documented. The procedure makes use of a single intracavity quarter-wave plate with its fast or gradual axis aligned parallel to the popular aircraft of polarization, described by an intracavity polarizer.

We report new experimental results around the phase-matching properties of yellow coloration HgGa2S4 crystals for harmonic technology of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers within the 0.944-ten.5910 μm selection. Also, we current new Sellmeier equations that supply a superior replica of your existing experimental effects plus the published knowledge factors for 2nd-harmonic technology of CO2 laser radiation at 9.

PA Ref-cell, which significantly lessens themeasurement glitches with the methane focus in thecase of instability

Two parametric four-wave-mixing (FWM) processes in Rb atoms are analyzed utilizing perturbation concept beneath the affliction of rotating wave approximation. The 2 parametric FWM processes are coupled when they're thrilled coherently by a short laser pulse with a bandwidth encompassing The 2 corresponding upper Electricity degrees in The 2 FWM procedures.

We existing a numerical analyze for the design of successful MgO:PPLN dependent pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of leading-hat transverse depth profile, as well as a double-move pump cavity configuration. Particularly, we look into the effect of domain shape to the conversion performance. We deemed two types of domain constructions: "best vertical-wall" and "wedge-formed" domains and our numerical final results display that at higher pump pulse energies, the conversion efficiency saturates, as well as the saturated efficiency is almost independent with the get more info area styles.

Assessment of recent, promising broad-band-gap nonlinear crystals with the mid-IR is supplied. We centered on ternary and quaternary chalcogenides and based on their own Bodily and chemical properties, which Together with linear and nonlinear optical properties, determine the effectiveness of crystal utilization in certain laser experiments. The correlation amongst the composition, framework and output parameters as well as the tendencies in improvements of the leading characteristics including band gap, nonlinear susceptibility, laser destruction threshold, and many others, are shown.

The defect chalcopyrite crystal HgGa2S4 has long been used in a very 1064-nm pumped optical parametric oscillator to generate Nonlinear crystals for optical parametric oscillators pumped by light-weight pulses of in close proximity to IR lasers...

A straightforward quantum product agrees properly Together with the experimental benefits and can make it probable to interpret the impact with regard to

three% rms above 12 h in very good beam quality. The around-IR sign pulses in the OPO Use a Gaussian pulse duration of �?19 ps , measured at 1284 nm. Now we have investigated the temperature tuning qualities with the OPO and compared the information While using the theoretical calculations making use of The newest Sellmeier equations and thermo-optic coefficients with the crystal. To the most effective of our know-how, this is the to start with picosecond OPO depending on CSP running at MHz repetition fees.
