053 μm. The absorption spectrum of ammonia was offered to demonstrate the feasibility of the developed optical parametric oscillator method for spectroscopic measurements and gasoline detection.
Output idler energies to the microjoule degree are attained with optimum conversion performance of 11% for your amplifier phase, that is over two times much better than the final results acquired having an analogous sample from the broadly distribute materials AgGaS 2 .
crystals with ultrafast Yb-ion laser pump is proposed. The final results sort a practical reference for the selection of materials
.. [Demonstrate comprehensive abstract] 3rd-harmonic era and parametric amplification with reduced-frequency pumping in periodically poled Lively nonlinear crystals may also be investigated. The Examination is carried out for the case of a periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of making use of periodically poled Energetic nonlinear crystals in laser units with self-frequency conversion are mentioned.
We report new experimental results to the stage-matching properties of yellow shade HgGa2S4 crystals for harmonic generation of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-10.5910 μm selection. In addition, we current new Sellmeier equations that give a fantastic reproduction with the present experimental benefits and also the published facts points for 2nd-harmonic generation of CO2 laser radiation at 9.
The substantial conversion effectiveness and wide selection of radiation wavelength tuning makes it possible for to count on that this product may perhaps compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Regardless of the sizeable difficulty of massive sizing crystals progress system.
Two parametric four-wave-mixing (FWM) procedures in Rb atoms are studied making use of perturbation principle beneath the ailment of rotating wave approximation. The 2 parametric FWM procedures are coupled when they are thrilled coherently by a short laser pulse using a bandwidth encompassing the two corresponding upper Vitality stages in the two FWM processes.
We present a numerical analyze for the design of efficient MgO:PPLN primarily based pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of major-hat transverse intensity profile, and a double-move pump cavity configuration. In particular, we investigate the result of domain form more info about the conversion effectiveness. We thought of two types of domain constructions: "great vertical-wall" and "wedge-formed" domains and our numerical outcomes present that at larger pump pulse energies, the conversion effectiveness saturates, and the saturated efficiency is sort of independent of your domain designs.
Vibrational spectra of Li-made up of nonlinear crystals as well as their software in THz radiation generation are mentioned. Working with an illustration of LiGaS2, the defect impact on spectroscopic features is demonstrated. High-temperature annealing in an appropriate ambiance lets 1 to eliminate extended and level defects and to Enhance the transparency. Electricity composition and parameters of principal place defects for instance anion vacancy (File-center) and cation antisite defect GaLi calculated from the main ideas concur properly with the experimental final results.
stabilize and tune the OPO, from which the stable etalon gave an improved effectiveness. Temperature oscillations within the PPLN crystal
Interference is noticed concerning the spontaneous parametric radiation from two nonlinear crystals separated by a macroscopic
The noticed f -to- two file frequency beats, originating directly from the OPO, can be used for self-referencing and stage locking on the pump laser comb without having for supercontinuum technology. With a median output energy of �?30 mW , this setup might be effective for a variety of spectroscopic programs inside the mid-IR.
In this paper we theoretically look into by far the most productive pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Evaluation contains solving the best Handle problem utilizing the rate equation formalism. The OPO best buildup conduct is derived for virtually any OPO configuration, and we present which the optimum pump pulse condition is really a double rectangle. The main rectangle is optimized for your buildup system, although the 2nd 1 is optimized for that constant state, and both equally depend otherwise around the OPO mirror reflectivities together with the accessible pump Electricity and maximum peak electricity.
Big difference frequency mixing of strongly targeted Gaussian beams in periodically poled LiNbO3 was investigated. The beams have been targeted Within the crystal without having injury. Mixing of cw and pulsed laser techniques was employed to minimize the thermal lensing consequences inside this crystal. A lower-electrical power cw 1.064‐μm Nd:YAG laser beam was utilized as the pump, Whilst the sign beam came from a picosecond optical .
