053 μm. The absorption spectrum of ammonia was introduced to exhibit the feasibility with the developed optical parametric oscillator technique for spectroscopic measurements and fuel detection.
Results of thermal conductivity measurements are reported for a number of of the greater not too long ago developed nonlinear optical crystals. New or significantly revised values of thermal conductivity have been acquired in six products. Noteworthy thermal conductivities calculated were Individuals for AgGaS2 [0.014 W/(cm K) and 0.

.. [Present entire abstract] third-harmonic technology and parametric amplification with minimal-frequency pumping in periodically poled Lively nonlinear crystals also are investigated. The Investigation is carried out for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Views of employing periodically poled Lively nonlinear crystals in laser products with self-frequency conversion are mentioned.
In this particular do the job, we present precisely what is, to our information, the primary measurements of the quantum phase diffusion sound of the cw OPO. Read a lot more
We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Which include sign and idler, it could be repeatedly tuned from 1.261 by way of 2.532 μm by different the pump wavelength. Two big enhancements were accomplished, including the link in the signal and idler tuning ranges plus the high output pulse Strength with the signal and idler tuning ... [Exhibit whole summary] ranges. The main improvement was achieved by getting two distinct sets of period-matching angles. The second improvement was realized by using five sets read more of resonator mirrors for oscillating either sign or idler.
Two parametric 4-wave-mixing (FWM) procedures in Rb atoms are researched using perturbation theory underneath the issue of rotating wave approximation. The two parametric FWM processes are coupled when they're fired up coherently by a brief laser pulse having a bandwidth encompassing the two corresponding upper Electricity concentrations in The 2 FWM processes.

Normalization from the absorption signals from the PAD is performed according to the absorption indicators inside the gasoline-stuffed
gas analyzers is completed. The formulated PA methane sensor is customized for placement over the UAV’s board. Unit
In this particular paper we theoretically examine by far the most economical pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Investigation contains solving the optimum Manage trouble using the charge equation formalism. The OPO optimal buildup conduct is derived for any OPO configuration, and we demonstrate the optimum pump pulse condition is often a double rectangle. The main rectangle is optimized for that buildup procedure, while the next a person is optimized for that continuous state, and each rely in a different way on the OPO mirror reflectivities along with the accessible pump Power and most peak electricity.
3% rms in excess of 12 h in very good beam top quality. The around-IR signal pulses from the OPO Have a very Gaussian pulse duration of �?19 ps , calculated at 1284 nm. We have now investigated the temperature tuning properties of the OPO and as opposed the information Using the theoretical calculations applying The newest Sellmeier equations and thermo-optic coefficients for the crystal. To the ideal of our information, This can be the 1st picosecond OPO according to CSP operating at MHz repetition charges.
