Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR change-frequency technology in OPGaAs
Success of thermal conductivity measurements are noted for many of the more not too long ago formulated nonlinear optical crystals. New or significantly revised values of thermal conductivity have been obtained in six components. Noteworthy thermal conductivities calculated ended up All those for AgGaS2 [0.014 W/(cm K) and 0.
The very first-principles density practical calculations are performed to study the geometries and electronic constructions of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite structures, and the optical properties of all crystals are investigated systematically. The results indicate that these compounds have similar band constructions as well as band hole decreases from S to Se to Te. For the linear optical Qualities, a few crystals exhibit excellent light-weight transmission during the IR and part obvious regions, and particularly, HgGa2S4 and HgGa2Se4 crystals possess average birefringence.
The large conversion efficiency and wide selection of radiation wavelength tuning permits to hope that this product may well compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals in spite of the substantial issue of huge size crystals development procedure.
Self-referenced octave-large subharmonic Hole optical parametric oscillator centered at three μm and pumped by an Er-fiber laser
This double rectangle is quantitatively described and it is according to prior effects reported while in the literature. Also, numerical simulations are accustomed to validate our analytical design on a doubly resonant OPO and display consistent outcomes. The numerical simulations also present that an exceptional prime-hat temporal profile could present performances incredibly near to those accomplished While using the best double rectangle.
Though working with an institutional account for this Internet site we don’t track any own, effectiveness, purposeful or 1st or third occasion connected information and facts.
A technique is formulated to solve the process of shortened equations describing parametric era in a very just one-frequency OPO cavity beneath nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals plus the ideal reflection coefficient from the output mirror are believed versus the pump Electrical power density Wp at distinct values on the OPO nonstationarity .
Vibrational spectra of Li-made up of nonlinear crystals and their software in THz radiation technology are talked over. Using an example of LiGaS2, the defect impact on spectroscopic properties is revealed. Higher-temperature annealing in an appropriate ambiance makes it possible for a person to get rid of extended and issue defects and to Enhance the transparency. Electrical power construction and parameters of major position defects for example anion vacancy (File-Middle) and cation antisite defect GaLi calculated from the initial principles agree well Along with the experimental results.

Normalization with the absorption alerts in the PAD is completed based on the absorption indicators from the gas-loaded
twelve μm and describe all frequency conversion strategies understood so far with them together with long term probable purposes. Keywords and phrases: Ternary and quaternary semiconductors, defect chalcopyrites, good solutions, nonlinear optical crystals, mid-infrared
Single-action sub-200 fs mid-infrared era from an optical parametric oscillator synchronously pumped by an erbium fiber laser
This is the initial example of a broadband OPO functioning across the molecular fingerprint area, and we display its potential by conducting broadband Fourier-remodel spectroscopy utilizing drinking water vapor along with a polystyrene reference regular.
