Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variation-frequency era in OPGaAs
We report on a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) depending on the Kerr-lens-manner-locked Ti:sapphire laser as being the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO based on the nonlinear crystal, CdSiP two , synchronously pumped internal to some MgO:PPLN femtosecond OPO, We now have created broadly tunable radiation throughout 5958�?117 nm employing swift static cavity hold off tuning, which has a most power of 64 μW at 6791 nm, restricted through the absorption in mirror substrates along with polarization-dependent intracavity losses.
A list of ~450 noncentrosymmetric sulfides has become noticed in reference to nonlinear optical Homes. It has been located that about the aircraft from the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned right into a rosette of two intersected ellipses of «acentricity».
Studies of practical pump laser technologies suited to ultrafast femtosecond OPOs dependant on CdSiP 2 are talked about, plus the favorable linear and nonlinear optical properties, along with exceptional section-matching characteristics of CdSiP 2 , are presented utilizing the most recent Sellmeier equations for the material. The described experimental benefits signify the best output pulse Strength and file regular electric power in the ultrafast picosecond and femtosecond time scales over the six–seven μm spectral array to this point.
Self-referenced octave-broad subharmonic GaP optical parametric oscillator centered at three μm and pumped by an Er-fiber laser
This double rectangle is quantitatively explained and is particularly in keeping with former effects reported while in the literature. Also, numerical simulations are accustomed to validate our analytical product over a doubly resonant OPO and show dependable outcomes. The numerical simulations also display that an ideal prime-hat temporal profile could offer performances pretty near the ones accomplished While using the optimum double rectangle.
Though working with an institutional account for this Web page we don’t observe any private, efficiency, useful or 1st or third occasion linked information and facts.
Pumping mid-IR optical parametric oscillators near 1 μm is eye-catching for its simplicity and ability scaling capability. To this goal, vast bandgap non-oxide nonlinear crystals are necessary.
Moreover, we performed a numerical simulation of chirped-pulse OPOs (CPOPOs) and exposed that the spectral profile in the output from a CPOPO was pertinent to equally the parametric achieve profile on the nonlinear crystal plus the intra-cavity significant-buy dispersion.
This paper opinions the new developments in crystal advancement and singly resonant optical parametric oscillators for that era of superior one pulse Electricity and normal powers within the mid-IR from 3 to ten μm.
Normalization with the absorption signals while in the PAD is performed according to the absorption indicators in the gasoline-crammed
Quantum mechanical based to start with theory calculations are already employed to obtain the device cell lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite construction for the first time. For this, we treated HgGa2S4 in two differing kinds of web-site symmetries in precisely the same Area team.
Single-stage sub-200 fs mid-infrared era from an optical parametric oscillator synchronously pumped by an erbium fiber laser
three% rms more than twelve h in good beam good quality. The in the vicinity of-IR signal pulses with the OPO Possess a Gaussian pulse period of �?19 ps , measured at 1284 nm. Now we have investigated the temperature tuning traits with the OPO and compared the information with the theoretical calculations get more info making use of The newest Sellmeier equations and thermo-optic coefficients for the crystal. To the top of our awareness, this is the very first picosecond OPO determined by CSP running at MHz repetition fees.
