and running problems for the sensible layout of substantial electrical power femtosecond optical parametric oscillators with excitation
Results of thermal conductivity measurements are claimed for various of the more lately formulated nonlinear optical crystals. New or significantly revised values of thermal conductivity were acquired in 6 products. Notable thermal conductivities measured ended up These for AgGaS2 [0.014 W/(cm K) and 0.

The substantial conversion efficiency and big selection of radiation wavelength tuning lets to expect that this substance may possibly compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals in spite of the sizeable issue of big sizing crystals development system.
We report new experimental success on the stage-matching Houses of yellow color HgGa2S4 crystals for harmonic era of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers within the 0.944-ten.5910 μm range. Moreover, we existing new Sellmeier equations that supply a fantastic replica from the current experimental final results in addition to the posted data factors for next-harmonic technology of CO2 laser radiation at 9.
PA Ref-cell, which appreciably decreases themeasurement errors on the methane focus in thecase of instability
The temperature dependence of refractive indices of optical elements is characterised Within this work by what we connect with their normalized thermo-optic coefficients. These are typically established experimentally as a result of interferometric measurements of thermal enlargement and of modifications in optical thickness at a few laser wavelengths as perform of temperature. A suitable vectorial formalism placed on these facts permits predicting the thermal evolution with the refractive index everywhere in the beneficial selection of transparency.
A method is made to solve the system of shortened equations describing parametric era in a very one-frequency OPO cavity beneath nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals plus the best reflection coefficient in the output mirror are believed compared to the pump Electrical power density Wp at distinct values with the OPO nonstationarity .
Modeling and experimental research on stage matching of second harmonic generation in several colour Hg Ga 2 S four crystals are completed. Utilizing the identified Sellmeier equations, the dispersion relation with weighting proportionally to limited-wavelength boundary of the crystal transparency band is proposed.

Simple approach for reducing the depolarization reduction resulting from thermally induced birefringence in reliable-condition lasers
Quantum mechanical centered initial basic principle calculations are already used to get the unit cell lattice parameters of mercury thiogallate (HgGa2S4) check here in defect stannite framework for the first time. For this, we dealt with HgGa2S4 in two different types of website symmetries in exactly the same Place group.
An easy quantum model agrees properly with the experimental success and can make it achievable to interpret the influence with regard to
Diode-pumped optical parametric oscillation has long been shown for The very first time to our expertise in an individual Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions soak up the 812-nm radiation to make 1084-nm laser oscillation.
