Optical parametric oscillator pumped at ~one µm with intracavity mid-IR variance-frequency generation in OPGaAs
It's got extensive been predicted which the period distinction between the sign and idler subharmonic outputs of an optical parametric oscillator (OPO) undergoes a random stroll system, just like the stage diffusion of the laser [one].

A straightforward method for lowering the reduction that is because of depolarization ensuing from thermally induced strain birefringence in stable-condition lasers is reported. The procedure works by using an individual intracavity quarter-wave plate with its quickly or gradual axis aligned parallel to the popular aircraft of polarization, outlined by an intracavity polarizer.
Self-referenced octave-wide subharmonic GaP optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
This double rectangle is quantitatively explained which is according to preceding final results documented from the literature. Also, numerical simulations are accustomed to validate our analytical product on the doubly resonant OPO and clearly show reliable outcomes. The numerical simulations also exhibit that an ideal leading-hat temporal profile could give performances pretty near those achieved with the optimal double rectangle.
Optical properties of orange phased HgGa2S4 crystal is investigated. Technology of tunable Center infrared radiation by 2nd harmonic of tunable CO2 laser radiation has long been shown. Second harmonic conversion efficiency with regard to other infrared crystal has also been reviewed.
Pumping mid-IR optical parametric oscillators close to 1 μm is eye-catching for its simplicity and power scaling capability. To this intention, vast bandgap non-oxide nonlinear crystals are wanted.
Modeling and check here experimental review on stage matching of 2nd harmonic generation in several color Hg Ga 2 S four crystals are carried out. Using the regarded Sellmeier equations, the dispersion relation with weighting proportionally to small-wavelength boundary from the crystal transparency band is proposed.
The know-how of escalating mercury thiogallate crystals (HgGa2S4) is enhanced and high-excellent bulk samples are made. The fundamental optical and thermal Qualities of such crystals are researched. The transmission spectra of mercury thiogallate are calculated and its nonlinear attributes such as the quadratic susceptibility, tuning curves, plus the optical-harm resistance will also be decided.
The defect chalcopyrite crystal HgGa2S4 has long been used within a 1064-nm pumped optical parametric oscillator to deliver Nonlinear crystals for optical parametric oscillators pumped by light pulses of close to IR lasers...
for your detection of molecular trace gasses. The oscillation threshold, output power and steadiness of The only resonant
A pulsed TEA CO2 laser was employed to analyze the outcome of pump radiation parameters (method framework, wavelength, and pulse duration), concentrating conditions, absorption coefficient, and temperature on the performance of conversion into the second harmonic and on angular dependences of period matching in ZnGeP2 crystals. Great agreement betweeen experimental and theoretical benefits is observed. Read more
three% rms above twelve h in great beam good quality. The near-IR sign pulses in the OPO Have a very Gaussian pulse length of �?19 ps , measured at 1284 nm. We now have investigated the temperature tuning attributes with the OPO and compared the data Along with the theoretical calculations applying The newest Sellmeier equations and thermo-optic coefficients with the crystal. To the very best of our understanding, this is the initial picosecond OPO according to CSP functioning at MHz repetition rates.
