053 μm. The absorption spectrum of ammonia was presented to display the feasibility with the produced optical parametric oscillator method for spectroscopic measurements and fuel detection.
Final results of thermal conductivity measurements are described for a number of of the greater lately made nonlinear optical crystals. New or considerably revised values of thermal conductivity were being attained in six resources. Notable thermal conductivities calculated ended up Those people for AgGaS2 [0.014 W/(cm K) and 0.
This method allows the Procedure of greatly tunable optical parametric oscillators2 (OPO) and subsequent variation frequency generators3 manufacturing tunable pulses of superior peak ability. The higher Power of the pump pulse trains has certain Added benefits to the operation of a synchronously pumped OPO, e.g., calm steadiness necessities, plus the likely to operate with massive cavity losses (e.g. metallic mirrors) letting significant tuning ranges with an individual set of mirrors and high output-coupling aspects for pulse shortening.
The idea of chemical transportation reactions (volatilization of a fabric by way of a low-risky chemical intermediate at a temperature T1 and again-response on the mixture at a temperature T2, using the temperature dependence on the chemical equilibrium involved) can be a important Instrument for rising single crystals of many supplies which can't be effortlessly attained in the melt.
We report new experimental results around the phase-matching Houses of yellow color HgGa2S4 crystals for harmonic era of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers during the 0.944-ten.5910 μm assortment. In addition, we current new Sellmeier equations that supply a fantastic reproduction with the present experimental effects and also the revealed data points for 2nd-harmonic generation of CO2 laser radiation at nine.
The calculated Main stage binding energies are when compared with These of HgS, Gasoline, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves to generally be impartial on the technological situations of crystal development. In distinction to your valence band spectrum, the distribution of electron states inside the bandgap of HgGa2S4 crystals is discovered to get strongly dependent upon the technological circumstances of crystal growth as demonstrated by the photoluminescence Assessment.
Though applying an institutional account for this Web-site we don’t observe any personalized, efficiency, functional or 1st or third social gathering linked info.
Pumping mid-IR optical parametric oscillators around 1 μm is appealing for its simplicity and ability scaling functionality. To this goal, huge bandgap non-oxide nonlinear crystals are essential.
The specific heat and thermal conductivity of HgGa2S4 are calculated. It can be concluded the blended Qualities of HgGa2S4 crystals can offer for them a leading posture Among the many resources Employed in nonlinear-optical equipment for mid-IR-frequency conversion.
This paper evaluations the recent developments in crystal development and singly resonant optical parametric oscillators for your era of large single pulse Power and typical powers in the mid-IR from three to 10 μm.
The defect chalcopyrite crystal HgGa2S4 has long been employed in a very 1064-nm pumped optical parametric oscillator to crank out Nonlinear crystals for optical parametric oscillators pumped by mild pulses of in close proximity to IR lasers...
for the detection of molecular trace gasses. The oscillation threshold, output ability and steadiness of The one resonant
A simple quantum design agrees more info well With all the experimental results and can make it doable to interpret the outcome with regard to
This is actually the first illustration of a broadband OPO functioning across the molecular fingerprint region, and we show its possible by conducting broadband Fourier-change spectroscopy using water vapor and also a polystyrene reference standard.
