Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR difference-frequency technology in OPGaAs
Output idler energies around the microjoule degree are acquired with greatest conversion effectiveness of eleven% to the amplifier phase, that is much more than two times much better than the results acquired having an analogous sample with the widely unfold product AgGaS two .
A set of ~450 noncentrosymmetric sulfides continues to be noticed in reference to nonlinear optical Houses. It has been uncovered that on the airplane in the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned into a rosette of two intersected ellipses of «acentricity».
Reports of practical pump laser systems ideal for ultrafast femtosecond OPOs based upon CdSiP two are talked over, and the favorable linear and nonlinear optical Qualities, and also one of a kind phase-matching characteristics of CdSiP 2 , are offered applying the most recent Sellmeier equations for the material. The explained experimental success symbolize the very best output pulse Electricity and history ordinary power inside the ultrafast picosecond and femtosecond time scales through the six–seven μm spectral range to date.
In this perform, we current exactly what is, to our understanding, the initial measurements in the quantum stage diffusion sound of a cw OPO. Examine a lot more
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Which includes sign and idler, it may be constantly tuned from 1.261 by way of two.532 μm by different the pump wavelength. Two significant enhancements have been achieved, including the connection from the sign and idler tuning ranges and also the large output pulse Vitality from the signal and idler tuning ... [Present complete summary] ranges. The primary improvement was obtained by getting two certain sets of section-matching angles. The second advancement was recognized by making use of five sets of resonator mirrors for oscillating either sign or idler.
Optical Attributes of orange phased HgGa2S4 crystal is investigated. Technology of tunable middle infrared radiation by 2nd harmonic of tunable CO2 laser radiation has long been shown. Next harmonic conversion efficiency with regard to other infrared crystal has also been mentioned.
A way is developed to solve the process of shortened equations describing parametric technology in a one particular-frequency OPO cavity less than nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals as well as optimum reflection coefficient from the output mirror are estimated compared to the pump Electrical power density Wp at distinctive values of the OPO nonstationarity .
Modeling and experimental review on period matching of 2nd harmonic technology in different coloration Hg Ga two S four crystals are carried out. Utilizing the recognized Sellmeier equations, the dispersion relation with weighting proportionally to shorter-wavelength boundary of the crystal transparency band is proposed.
The know-how of growing mercury thiogallate crystals (HgGa2S4) is improved and superior-quality bulk samples are developed. The fundamental optical and thermal properties of these crystals are examined. The transmission spectra of mercury thiogallate are measured and its nonlinear traits including the quadratic susceptibility, tuning curves, and the optical-damage resistance are also determined.
... The initial knowledge around the refractive index of orange HGS printed by Levine et al. [35] included only couple wavelengths in the noticeable and in the vicinity of-IR just as an illustration from the feasibility of this crystal for birefringent period-matching. The refractive indices with the orange stage ended up calculated click here and tabulated concerning 0.
twelve μm and describe all frequency conversion schemes realized thus far with them and foreseeable future possible applications. Keywords: Ternary and quaternary semiconductors, defect chalcopyrites, strong remedies, nonlinear optical crystals, mid-infrared
During this paper we theoretically investigate quite possibly the most effective pump temporal form for pulsed operation of optical parametric oscillators (OPOs). The theoretical analysis is made up of fixing the best Regulate dilemma utilizing the price equation formalism. The OPO ideal buildup habits is derived for any OPO configuration, and we demonstrate that the exceptional pump pulse shape is usually a double rectangle. The very first rectangle is optimized to the buildup process, while the 2nd a single is optimized for your continual state, and both count in another way about the OPO mirror reflectivities together with the out there pump Vitality and highest peak electric power.
three% rms more than 12 h in excellent beam good quality. The in the vicinity of-IR signal pulses in the OPO Have got a Gaussian pulse duration of �?19 ps , calculated at 1284 nm. We've investigated the temperature tuning features from the OPO and when compared the information Using the theoretical calculations employing The latest Sellmeier equations and thermo-optic coefficients to the crystal. To the best of our knowledge, This is actually the to start with picosecond OPO based upon CSP functioning at MHz repetition prices.
