Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR big difference-frequency technology in OPGaAs
A method-locked tunable dye laser continues to be produced which happens to be synchronously pumped at significant repetition charges because of the doubled output of the manner-locked Nd:YAG laser. The dye laser provides powerful pulses of 35 psec length which might be extensively tunable, of in the vicinity of-renovate-minimal bandwidth, and in time coincidence While using the pumping pulses.
The primary-ideas density practical calculations are carried out to study the geometries and Digital buildings of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite constructions, as well as the optical Homes of all crystals are investigated systematically. The results suggest that these compounds have identical band buildings as well as band gap decreases from S to Se to Te. For your linear optical Qualities, a few crystals exhibit very good light transmission in the IR and aspect noticeable areas, and particularly, HgGa2S4 and HgGa2Se4 crystals have moderate birefringence.
In both equally the cases acquired device mobile parameters are same, which shows the accuracy of current tactic. The Digital band structures exhibit the semiconducting conduct in equally the conditions. The density of states plot also are examined and discussed.
Self-referenced octave-vast subharmonic Hole optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
The measured core degree binding energies are compared with These of HgS, Gasoline, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves for being independent about the technological ailments of crystal advancement. In contrast to the valence band spectrum, the distribution of electron states inside the bandgap of HgGa2S4 crystals is discovered to become strongly dependent on the technological disorders of crystal development as demonstrated with the photoluminescence Evaluation.
The temperature dependence of refractive indices of optical components is characterized During this function by what we phone their normalized thermo-optic coefficients. These are determined experimentally by means of interferometric measurements of thermal growth and of improvements in optical thickness at a handful of laser wavelengths as function of temperature. A suitable vectorial formalism applied to these information will allow predicting the thermal evolution in the refractive index all around the helpful range of transparency.
A technique is designed to solve the process of shortened equations describing parametric generation inside of a a single-frequency OPO cavity less than nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals plus the optimum reflection here coefficient of your output mirror are estimated as opposed to the pump energy density Wp at diverse values in the OPO nonstationarity .
Reliable point out polymerization of diacetylenes The crystal structure of HAlSi2O6 using a keatite-form framework Syntheses and crystal constructions of α
stabilize and tune the OPO, from which the reliable etalon gave an even better general performance. Temperature oscillations in the PPLN crystal
... The initial facts around the refractive index of orange HGS released by Levine et al. [35] bundled only couple wavelengths inside the obvious and near-IR just as an illustration of the feasibility of this crystal for birefringent period-matching. The refractive indices with the orange phase had been calculated and tabulated concerning 0.
Quantum mechanical centered to start with basic principle calculations are already utilized to obtain the device mobile lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite construction for the first time. For this, we treated HgGa2S4 in two different types of web page symmetries in a similar Place group.
With this paper we theoretically investigate by far the most productive pump temporal form for pulsed operation of optical parametric oscillators (OPOs). The theoretical Investigation is made up of solving the best Handle problem utilizing the price equation formalism. The OPO optimum buildup actions is derived for almost any OPO configuration, and we display the optimal pump pulse form is really a double rectangle. The main rectangle is optimized to the buildup process, even though the 2nd one particular is optimized with the constant point out, and each rely differently about the OPO mirror reflectivities as well as the obtainable pump Electricity and maximum peak electricity.
This is actually the 1st illustration of a broadband OPO functioning through the molecular fingerprint location, and we demonstrate its possible by conducting broadband Fourier-change spectroscopy employing drinking water vapor and also a polystyrene reference conventional.
