Optical parametric oscillator pumped at ~one µm with intracavity mid-IR change-frequency technology in OPGaAs
It's lengthy been predicted that the period distinction between the signal and idler subharmonic outputs of the optical parametric oscillator (OPO) undergoes a random wander approach, similar to the stage diffusion of a laser [one].
A set of ~450 noncentrosymmetric sulfides has become noticed in reference to nonlinear optical Houses. It's been uncovered that on the airplane from the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned right into a rosette of two intersected ellipses of «acentricity».
By implementing intracavity dispersion Regulate, in close proximity to-remodel-limited signal pulses of �?100 fs length with sleek one-peak spectrum are obtained at 1264 nm, corresponding to an idler wavelength at 6440 nm. To the best of our understanding, This can be The 1st time this kind of useful idler powers in the deep-IR have been generated from a dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition level.
Self-referenced octave-large subharmonic Hole optical parametric oscillator centered at three μm and pumped by an Er-fiber laser
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Including signal and idler, it may be constantly tuned from one.261 by means of two.532 μm by various the pump wavelength. Two big advancements ended up realized, including the link of the signal and idler tuning ranges as well as the high output pulse Electricity with the sign and idler tuning ... [Clearly show total summary] ranges. The initial advancement was attained by getting two unique sets of stage-matching angles. The 2nd improvement was understood by utilizing 5 sets of resonator mirrors for oscillating possibly signal or idler.
Even though utilizing an institutional account for this Web site we don’t observe any individual, functionality, practical or 1st or third party associated info.
We present a numerical review for the look of successful MgO:PPLN centered pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of top rated-hat transverse depth profile, in addition to a double-go pump cavity configuration. Particularly, we investigate the outcome of domain condition about the conversion efficiency. We regarded two forms of domain buildings: "fantastic vertical-wall" and "wedge-shaped" domains and our numerical outcomes present that at higher pump pulse energies, the conversion efficiency saturates, plus the saturated performance is nearly unbiased from the domain designs.
The precise warmth and thermal conductivity of HgGa2S4 are measured. It really is concluded the combined properties of HgGa2S4 crystals can offer for them a number one situation among the components Utilized in nonlinear-optical units for mid-IR-frequency conversion.
stabilize and tune the OPO, from which the good etalon gave a far better effectiveness. Temperature oscillations during the PPLN crystal
... The primary knowledge to the refractive index of orange HGS revealed by Levine et al. [35] integrated only few wavelengths within the noticeable and around-IR equally as an illustration of the feasibility of this crystal for birefringent phase-matching. The refractive indices to the orange period had been measured website and tabulated in between 0.
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser process. By employing a three hundred μm lengthy magnesium-doped periodically poled LiNbO 3 crystal given that the parametric get medium and configuring the OPO to be a chirped-pulse oscillator, we obtained mid-infrared emission possessing an instantaneous bandwidth masking 3084�?466 nm. This consequence signifies, to the best of our expertise, the widest instantaneous bandwidth obtained from the Yb-fiber-laser-pumped singly resonant OPO, demonstrating the immense potential of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-rapid OPOs.
Recent mid-IR NLO crystals is usually divided into 4 groups, i.e., classical binary and ternary steel pnictides and chalcogenides, quaternary steel chalcogenides, binary and ternary metallic halides, and different-bond-style hybrid compounds that consist of at least two kinds of certainly different chemical bonds inside the crystal structures. Metal pnictides and chalcogenides have acquired Considerably interest on increasing big crystals. Diverse-bond-style hybrid is a whole new loved ones of mid-IR NLO components, and many of these have been located in the last decade. In metal halide process, both of those progress in expanding significant crystals and identifying new kinds are already designed.
Here is the first illustration of a broadband OPO running across the molecular fingerprint region, and we reveal its likely by conducting broadband Fourier-renovate spectroscopy using drinking water vapor along with a polystyrene reference common.
