053 μm. The absorption spectrum of ammonia was introduced to display the feasibility of the developed optical parametric oscillator process for spectroscopic measurements and gas detection.
Results of thermal conductivity measurements are claimed for several of the more not long ago designed nonlinear optical crystals. New or significantly revised values of thermal conductivity have been acquired in 6 supplies. Noteworthy thermal conductivities measured were These for AgGaS2 [0.014 W/(cm K) and 0.
A set of ~450 noncentrosymmetric sulfides has been noticed in reference to nonlinear optical Homes. It has been found that on the airplane on 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 control, in close proximity to-remodel-confined signal pulses of �?one hundred fs duration with clean one-peak spectrum are reached at 1264 nm, equivalent to an idler wavelength at 6440 nm. To the best of our expertise, This really is The very first time such useful idler powers during the deep-IR have already been created from a dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition charge.
We report new experimental final results around the stage-matching properties of yellow coloration HgGa2S4 crystals for harmonic era of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers inside the 0.944-10.5910 μm vary. In addition, we present new Sellmeier equations that supply a excellent replica of the current experimental success along with the published facts factors for 2nd-harmonic era of CO2 laser radiation at 9.
PA Ref-cell, which appreciably minimizes themeasurement mistakes of your methane concentration in thecase of instability
The generation of tunable pico- and femtosecond light-weight pulses with parametric frequency conversion processes has attracted greater consideration recently1. New crystal resources, as BBO, LBO, and KTP, with remarkable nonlinearity and higher destruction threshold are now readily available, and pump lasers of enhanced steadiness allow the trustworthy Procedure of optical parametric oscillators. Parametric devices pumped ... [Show entire abstract] both by cw read more modelocked lasers or by solitary intense ultrashort pulses are already developed. During this contribution parametric techniques are discussed that happen to be pumped by rigorous pulse trains of some microseconds length and repetition costs as much as 50Hz.
This new edition has actually been updated and revised to includeimportant developments, concepts and technologies that haveemerged since the publication of the main version.
In addition, we carried out a numerical simulation of chirped-pulse OPOs (CPOPOs) and uncovered that the spectral profile from the output from a CPOPO was related to each the parametric acquire profile from the nonlinear crystal as well as the intra-cavity large-purchase dispersion.
stabilize and tune the OPO, from which the good etalon gave an improved functionality. Temperature oscillations from the PPLN crystal
Normalization of your absorption indicators inside the PAD is completed according to the absorption alerts in the fuel-crammed
for the detection of molecular trace gasses. The oscillation threshold, output power and steadiness of the single resonant
A pulsed TEA CO2 laser was made use of to investigate the effect of pump radiation parameters (mode structure, wavelength, and pulse period), concentrating disorders, absorption coefficient, and temperature on the performance of conversion into the 2nd harmonic and on angular dependences of section matching in ZnGeP2 crystals. Superior settlement betweeen experimental and theoretical effects is noticed. Go through a lot more
three% rms more than twelve h in good beam excellent. The close to-IR sign pulses from the OPO Have a very Gaussian pulse period of �?19 ps , calculated at 1284 nm. We now have investigated the temperature tuning attributes with the OPO and compared the data Using the theoretical calculations employing the most recent Sellmeier equations and thermo-optic coefficients for the crystal. To the most effective of our awareness, This is actually the initially picosecond OPO according to CSP running at MHz repetition charges.
