Optical parametric oscillator pumped at ~one µm with intracavity mid-IR difference-frequency generation in OPGaAs
Output idler energies on the microjoule level are received with most conversion efficiency of 11% for the amplifier stage, which is a lot more than two situations better than the results received with the analogous sample from the greatly unfold material AgGaS two .
A set of ~450 noncentrosymmetric sulfides has been noticed in reference to nonlinear optical Homes. It has been identified that over 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 applying intracavity dispersion Management, in the vicinity of-remodel-constrained signal pulses of �?a hundred fs period with sleek solitary-peak spectrum are accomplished at 1264 nm, corresponding to an idler wavelength at 6440 nm. To the most beneficial of our expertise, This can be The very first time these kinds of useful idler powers inside the deep-IR are already created from a dispersion-compensated CSP femtosecond OPO at sub-one hundred MHz repetition fee.
OPO had been improved by optimizing pump beam waist and OPO cavity length. Both equally air-spaced and strong etalons were examined to frequency
PA Ref-mobile, which drastically decreases themeasurement mistakes of your methane concentration in thecase of instability
Two parametric four-wave-mixing (FWM) procedures in Rb atoms are researched using perturbation idea underneath the ailment of rotating wave approximation. The two parametric FWM processes are coupled when they are energized coherently by a brief laser pulse using a bandwidth encompassing the two corresponding upper Electricity ranges in the two FWM processes.
air gap and thrilled in series by a common pump beam. The stage on the interference is determined by the stage shifts at 3 frequencies.

This paper opinions the modern developments in crystal development and singly resonant optical parametric oscillators with the technology of higher one pulse Electrical power and normal powers while in the mid-IR from 3 to 10 μm.
... The very first information to the refractive index of orange HGS posted by Levine et al. [35] incorporated only couple wavelengths from the seen and near-IR just as an illustration with the feasibility of the crystal for birefringent stage-matching. The refractive indices to the orange period were being measured and tabulated among 0.
The observed file -to- two file frequency beats, originating directly from the OPO, can be used for self-referencing and phase locking with the pump laser comb without having for supercontinuum generation. With an average output ability of �?30 mW , this setup could possibly be helpful for a range of spectroscopic purposes in the mid-IR.
A pulsed TEA CO2 laser was employed to analyze the influence of pump radiation parameters (mode framework, wavelength, and pulse length), concentrating ailments, absorption click here coefficient, and temperature about the efficiency of conversion into the second harmonic and on angular dependences of section matching in ZnGeP2 crystals. Great settlement betweeen experimental and theoretical results is observed. Browse far more
This can be the first illustration of a broadband OPO operating through the molecular fingerprint region, and we exhibit its prospective by conducting broadband Fourier-transform spectroscopy applying h2o vapor in addition to a polystyrene reference normal.
