.. [Present complete abstract] parametric oscillator. The two independently targeted beams ended up designed to overlap Within the crystal. The focusing parameters of The 2 beams were regarding the exact same. The focusing perform produced by Boyd and Kleinman for tightly centered beams was extended to periodically poled crystals in order to in shape the temperature-tuning curve. A 0.sixty six%/W effectiveness was received for the difference frequency mixing process.
Final results of thermal conductivity measurements are reported for various of the more a short while ago produced nonlinear optical crystals. New or substantially revised values of thermal conductivity were being obtained in six supplies. Notable thermal conductivities measured were being Those people for AgGaS2 [0.014 W/(cm K) and 0.
The main-rules density purposeful calculations are done to check the geometries and Digital constructions of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite constructions, as well as optical Houses of all crystals are investigated systematically. The outcome reveal that these compounds have very similar band structures as well as band hole decreases from S to Se to Te. To the linear optical properties, a few crystals demonstrate excellent light transmission from the IR and portion visible areas, and in particular, HgGa2S4 and HgGa2Se4 crystals possess average birefringence.
.. [Show total summary] third-harmonic generation and parametric amplification with minimal-frequency pumping in periodically poled Energetic nonlinear crystals also are investigated. The Evaluation is performed for the case of the periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of working with periodically poled active nonlinear crystals in laser equipment with self-frequency conversion are talked about.
OPO were being improved by optimizing pump beam waistline and OPO cavity length. Equally air-spaced and reliable etalons were being examined to frequency
The calculated Main amount binding energies are compared with Individuals of HgS, Gasoline, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves to become independent on the technological conditions of crystal advancement. In distinction on the valence band spectrum, the distribution of electron states while in the bandgap of HgGa2S4 crystals is observed to generally be strongly dependent on the technological situations of crystal development as shown with the photoluminescence Evaluation.
Taxonomy, chemical bonding relations and nonlinear optical Attributes of noncentrosymmetric sulfide crystals

Higher-buy nonlinear procedures in option supplies are regarded along with a discussion on content suitability for down-conversion of near-IR lasers into the mid-IR to satisfy a variety of application needs is additionally introduced.
The technological know-how of rising mercury thiogallate crystals (HgGa2S4) is improved and high-high-quality bulk samples are developed. The essential optical and thermal Homes of such crystals are analyzed. The transmission spectra of mercury thiogallate are measured and its nonlinear features like the quadratic susceptibility, tuning curves, and the optical-hurt resistance also are decided.
Normalization with the absorption signals while in the PAD is performed according to the absorption indicators during the gasoline-filled
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser technique. By employing a three hundred μm extended magnesium-doped periodically poled LiNbO three crystal as being the parametric acquire medium click here and configuring the OPO as a chirped-pulse oscillator, we received mid-infrared emission obtaining an instantaneous bandwidth covering 3084�?466 nm. This consequence signifies, to the very best of our understanding, the widest instantaneous bandwidth acquired from a Yb-fiber-laser-pumped singly resonant OPO, demonstrating the enormous opportunity of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-quickly OPOs.
Solitary-step sub-two hundred fs mid-infrared era from an optical parametric oscillator synchronously pumped by an erbium fiber laser
Change frequency mixing of strongly concentrated Gaussian beams in periodically poled LiNbO3 was investigated. The beams were being concentrated In the crystal with no hurt. Mixing of cw and pulsed laser methods was utilized to attenuate the thermal lensing results inside of this crystal. A lower-electrical power cw one.064‐μm Nd:YAG laser beam was applied given that the pump, whereas the sign beam arrived from a picosecond optical .
