Optical parametric oscillator pumped at ~one µm with intracavity mid-IR difference-frequency technology in OPGaAs
Final results of thermal conductivity measurements are reported for several of the more recently made nonlinear optical crystals. New or significantly revised values of thermal conductivity have been obtained in 6 resources. Noteworthy thermal conductivities measured were Those people for AgGaS2 [0.014 W/(cm K) and 0.
The 1st-concepts density functional calculations are executed to study the geometries and electronic buildings of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite buildings, along with the optical properties of all crystals are investigated systematically. The outcomes show that these compounds have equivalent band constructions as well as the band hole decreases from S to Se to Te. For that linear optical Houses, 3 crystals demonstrate excellent light transmission within the IR and part seen regions, and especially, HgGa2S4 and HgGa2Se4 crystals have moderate birefringence.
.. [Present whole abstract] third-harmonic era and parametric amplification with lower-frequency pumping in periodically poled Energetic nonlinear crystals are investigated. The Assessment is carried out for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of employing periodically poled active nonlinear crystals in laser devices with self-frequency conversion are talked about.
We report new experimental effects about the stage-matching Attributes of yellow colour HgGa2S4 crystals for harmonic generation of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers while in the 0.944-10.5910 μm range. Additionally, we present new Sellmeier equations that offer a great replica in the present experimental effects together with the printed facts points for 2nd-harmonic technology of CO2 laser radiation at 9.
This double rectangle is quantitatively explained which is according to former effects documented within the literature. Also, numerical simulations are utilized to validate our analytical design on the doubly resonant OPO and show consistent effects. The numerical simulations also present that an optimum top-hat temporal profile could deliver performances quite close to the ones obtained with the best double rectangle.
The temperature dependence of refractive indices of optical elements is characterized With this work by what we phone their normalized thermo-optic coefficients. These are typically established experimentally by way of interferometric measurements of thermal enlargement and of adjustments in optical thickness at a number of laser wavelengths as purpose of temperature. An acceptable vectorial formalism placed on these information makes it possible for predicting the thermal evolution with the refractive index everywhere in the helpful variety of transparency.
Pumping mid-IR optical parametric oscillators in the vicinity of one μm is appealing for its simplicity and energy scaling functionality. To this intention, wide bandgap non-oxide nonlinear crystals are wanted.
