.. [Exhibit comprehensive summary] parametric oscillator. The two independently focused beams had been built to overlap In the crystal. The concentrating parameters of the two beams ended up with regards to the same. The focusing function developed by Boyd and Kleinman for tightly targeted beams was prolonged to periodically poled crystals so as to in shape the temperature-tuning curve. A 0.sixty six%/W performance was received for the difference frequency mixing procedure.
Final results of thermal conductivity measurements are claimed for many of the more recently formulated nonlinear optical crystals. New or considerably revised values of thermal conductivity were attained in six products. Notable thermal conductivities measured have been Individuals for AgGaS2 [0.014 W/(cm K) and 0.

The principle of chemical transportation reactions (volatilization of a fabric by using a minimal-risky chemical intermediate in a temperature T1 and back-reaction of the mixture in a temperature T2, using the temperature dependence on the chemical equilibrium associated) can be a valuable tool for rising single crystals of many components which can't be easily received within the melt.
We report new experimental effects to the stage-matching Qualities of yellow coloration HgGa2S4 crystals for harmonic era of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-ten.5910 μm assortment. Additionally, we current new Sellmeier equations that provide a great replica from the existing experimental outcomes as well as the released data factors for next-harmonic generation of CO2 laser radiation at nine.
The substantial conversion performance and big selection of radiation wavelength tuning enables to count on that this substance may perhaps compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Regardless of the considerable problems of huge dimensions crystals advancement procedure.
The temperature dependence of refractive indices of optical supplies is characterized With this perform by what we call their normalized thermo-optic coefficients. These are generally decided experimentally by means of interferometric measurements of thermal growth and of variations in optical thickness at a couple of laser wavelengths as operate of temperature. An appropriate vectorial formalism applied to these info lets predicting the thermal evolution of the refractive index all over the valuable number of transparency.
We existing a numerical review for the design of efficient MgO:PPLN based mostly pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of top rated-hat transverse intensity profile, in addition to a double-move pump cavity configuration. In particular, we look into the effect of domain shape around the conversion performance. We considered two kinds of area constructions: "great vertical-wall" and "wedge-formed" domains and our numerical outcomes present that at higher pump pulse energies, the conversion efficiency saturates, and also the saturated efficiency is sort of independent in the area styles.
Vibrational spectra of Li-containing nonlinear crystals and their application in THz radiation technology are talked about. Applying an example of LiGaS2, the defect effect on spectroscopic features is shown. Substantial-temperature annealing in an appropriate atmosphere permits just one to remove extended and point defects and to Enhance the transparency. Electricity composition and parameters of primary place defects like anion vacancy (F-Middle) and cation antisite defect GaLi calculated from the primary concepts concur perfectly Using the experimental final results.
Investigation of latest, promising large-band-gap nonlinear crystals for that mid-IR is given. We focused on ternary and quaternary chalcogenides and dependent on their Bodily and chemical Attributes, which As well as linear and nonlinear optical Houses, determine the efficiency of crystal utilization in sure laser experiments. The correlation in between the composition, framework and output parameters and also the trends in alterations of the most crucial traits for example band hole, nonlinear susceptibility, laser harm threshold, and so forth, are shown.
Straightforward system for reducing the depolarization loss resulting from thermally induced birefringence in reliable-point out lasers
with the detection of molecular trace gasses. The oscillation threshold, output power and stability of the single resonant
On this paper we theoretically investigate probably the most efficient pump temporal condition for pulsed operation of optical parametric oscillators (OPOs). The theoretical analysis contains fixing the optimal Regulate issue utilizing the charge equation formalism. The OPO best buildup behavior is derived for just about any OPO configuration, and we display the exceptional pump pulse shape is actually a double rectangle. The initial rectangle is optimized to the buildup procedure, while the next 1 click here is optimized for that continuous state, and both of those depend in another way to the OPO mirror reflectivities along with the obtainable pump energy and optimum peak ability.
Diode-pumped optical parametric oscillation has been demonstrated for The very first time to our knowledge in an individual Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions take up the 812-nm radiation to create 1084-nm laser oscillation.
