Optical parametric oscillator pumped at ~one µm with intracavity mid-IR change-frequency era in OPGaAs
Results of thermal conductivity measurements are claimed for quite a few of the more a short while ago designed nonlinear optical crystals. New or significantly revised values of thermal conductivity have been obtained in six materials. Notable thermal conductivities measured were being All those for AgGaS2 [0.014 W/(cm K) and 0.

A simple approach for lowering the loss that is because of depolarization resulting from thermally induced anxiety birefringence in strong-point out lasers is documented. The approach utilizes a single intracavity quarter-wave plate with its rapid or sluggish axis aligned parallel to the preferred airplane of polarization, defined by an intracavity polarizer.
A laser gas analyzer has actually been made for analyzing the composition of exhaled air by way of photoacoustic spectroscopy. The analyzer, based upon a broadband optical parametric oscillator and photoacoustic detector, provides large-precision immediate Evaluation on the multicomponent composition of human exhaled air for dynamic estimation of the efficiency of dealing with bronchus and lung diseases.
caused oscillations inside the idler wavelength of below 200MHz about 300s; the shorter-time period stability was less than 3MHz
The temperature dependence of refractive indices of optical materials is characterized During this perform by what we connect with their normalized thermo-optic coefficients. These are generally identified experimentally via interferometric measurements of thermal growth and of variations in optical thickness at a few laser wavelengths as operate of temperature. An appropriate vectorial formalism placed on these data permits predicting the thermal evolution with the refractive index everywhere in the useful array of transparency.
air hole and psyched in series by a standard pump beam. The period of your interference will depend on the phase shifts at 3 frequencies.

The engineering of expanding mercury thiogallate crystals (HgGa2S4) is improved and substantial-good quality bulk samples are created. The essential optical and thermal Homes of such crystals are analyzed. The transmission spectra of mercury thiogallate are measured and its nonlinear properties like the quadratic susceptibility, tuning curves, and the optical-problems resistance can also be decided.
The defect chalcopyrite crystal HgGa2S4 has been used in a very 1064-nm pumped optical parametric oscillator to make Nonlinear crystals for optical parametric oscillators pumped by mild pulses of close to IR lasers...
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser system. By using a 300 μm very long magnesium-doped periodically poled LiNbO three crystal because the parametric achieve medium and configuring the OPO to be a chirped-pulse oscillator, we obtained mid-infrared emission possessing an instantaneous bandwidth covering 3084�?466 nm. This consequence HgGa2S4 Crystal signifies, to the best of our understanding, the widest instantaneous bandwidth acquired from a Yb-fiber-laser-pumped singly resonant OPO, demonstrating the enormous probable of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-rapid OPOs.
Within this paper we theoretically look into quite possibly the most economical pump temporal condition for pulsed operation of optical parametric oscillators (OPOs). The theoretical Examination is made up of resolving the optimal Handle dilemma using the charge equation formalism. The OPO optimal buildup habits is derived for any OPO configuration, and we present the exceptional pump pulse form is a double rectangle. The first rectangle is optimized for the buildup system, when the next just one is optimized to the regular point out, and each count in a different way around the OPO mirror reflectivities and also the available pump Electricity and highest peak ability.
Difference frequency mixing of strongly centered Gaussian beams in periodically poled LiNbO3 was investigated. The beams had been concentrated inside the crystal devoid of injury. Mixing of cw and pulsed laser units was utilized to minimize the thermal lensing outcomes inside of this crystal. A small-electricity cw one.064‐μm Nd:YAG laser beam was utilised given that the pump, Whilst the sign beam arrived from the picosecond optical .
