and functioning conditions for the sensible style and design of higher electric power femtosecond optical parametric oscillators with excitation
Output idler energies within the microjoule amount are obtained with greatest conversion performance of eleven% for the amplifier phase, and that is in excess of two times better than the outcome attained with the analogous sample from the widely spread material AgGaS 2 .
The very first-principles density functional calculations are performed to study the geometries and Digital buildings of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite buildings, and the optical Attributes of all crystals are investigated systematically. The final results point out that these compounds have similar band structures as well as band gap decreases from S to Se to Te. To the linear optical Attributes, three crystals present superior light-weight transmission in the IR and component obvious locations, and particularly, HgGa2S4 and HgGa2Se4 crystals possess moderate birefringence.
By applying intracavity dispersion control, in close proximity to-change-limited signal pulses of �?a hundred fs duration with clean one-peak spectrum are realized at 1264 nm, equivalent to an idler wavelength at 6440 nm. To the most beneficial of our awareness, this is the first time this kind of realistic idler powers within the deep-IR are generated from a dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition level.
Self-referenced octave-huge subharmonic Hole optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
PA Ref-cell, which substantially lessens themeasurement faults of the methane concentration in thecase of instability
Even though making use of an institutional account for this website we don’t keep track of any private, performance, functional or 1st or 3rd party similar info.
We existing a numerical examine for the design of effective MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of prime-hat more info transverse intensity profile, and a double-move pump cavity configuration. Particularly, we investigate the outcome of area condition about the conversion effectiveness. We regarded as two types of area structures: "fantastic vertical-wall" and "wedge-formed" domains and our numerical outcomes show that at better pump pulse energies, the conversion efficiency saturates, as well as saturated effectiveness is almost unbiased on the domain designs.

... The first info over the refractive index of orange HGS printed by Levine et al. [35] provided only few wavelengths while in the obvious and near-IR just as a demonstration from the feasibility of this crystal for birefringent phase-matching. The refractive indices with the orange stage were calculated and tabulated in between 0.
The observed file -to- 2 file frequency beats, originating straight from the OPO, can be used for self-referencing and section locking with the pump laser comb with no need for supercontinuum technology. With a median output energy of �?30 mW , this setup could be advantageous for many different spectroscopic applications while in the mid-IR.
A straightforward quantum design agrees well Using the experimental success and causes it to be feasible to interpret the result with regard to
three% rms above twelve h in superior beam quality. The near-IR signal pulses from the OPO Use a Gaussian pulse length of �?19 ps , calculated at 1284 nm. We've investigated the temperature tuning properties in the OPO and compared the information Using the theoretical calculations applying The newest Sellmeier equations and thermo-optic coefficients for that crystal. To the very best of our expertise, this is the to start with picosecond OPO based on CSP working at MHz repetition charges.
