.. [Demonstrate full abstract] parametric oscillator. The two independently centered beams were made to overlap In the crystal. The concentrating parameters of The 2 beams were in regards to the similar. The concentrating operate made by Boyd and Kleinman for tightly centered beams was extended to periodically poled crystals as a way to in good shape the temperature-tuning curve. A 0.66%/W effectiveness was attained for the difference frequency mixing procedure.
Output idler energies to the microjoule amount are received with greatest conversion effectiveness of 11% for that amplifier stage, that is greater than two periods a lot better than the results received by having an analogous sample of the commonly unfold material AgGaS two .
This system allows the operation of commonly tunable optical parametric oscillators2 (OPO) and subsequent change frequency generators3 manufacturing tunable pulses of superior peak power. The upper Power of your pump pulse trains has selected Rewards with the Procedure of the synchronously pumped OPO, e.g., relaxed stability demands, and the prospective to operate with large cavity losses (e.g. metal mirrors) letting large tuning ranges with only one set of mirrors and significant output-coupling factors for pulse shortening.
A simple procedure for decreasing the loss that is because of depolarization resulting from thermally induced worry birefringence in solid-point out lasers is described. The procedure makes use of only one intracavity quarter-wave plate with its fast or gradual axis aligned parallel to the popular plane of polarization, outlined by an intracavity polarizer.
We report new experimental benefits on the phase-matching Homes of yellow coloration HgGa2S4 crystals for harmonic era of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers within the 0.944-10.5910 μm selection. Also, we current new Sellmeier equations that supply a great reproduction of your existing experimental benefits and also the published data points for second-harmonic era of CO2 laser radiation at 9.
During this Introduction We are going to give a limited overview with the crucial milestones in the development of solid-state lasers, focus on the variety of general performance parameters feasible with these lasers, and point out major programs.
Two parametric four-wave-mixing (FWM) processes in Rb atoms are researched employing perturbation idea under the affliction of rotating wave approximation. The two parametric FWM procedures are coupled when they're fired up coherently by a brief laser pulse with a bandwidth encompassing The 2 corresponding higher energy amounts in The 2 FWM processes.

Assessment of latest, promising large-band-hole nonlinear crystals for the mid-IR is presented. We centered on ternary and quaternary chalcogenides and centered on their own Bodily and chemical website properties, which Besides linear and nonlinear optical Attributes, figure out the efficiency of crystal utilization in certain laser experiments. The correlation among the composition, structure and output parameters and also the traits in modifications of the principle qualities for example band hole, nonlinear susceptibility, laser destruction threshold, and so forth, are shown.
The defect chalcopyrite crystal HgGa2S4 continues to be utilized in the 1064-nm pumped optical parametric oscillator to produce Nonlinear crystals for optical parametric oscillators pumped by light pulses of around IR lasers...
12 μm and explain all frequency conversion schemes understood to this point with them along with future potential applications. Key phrases: Ternary and quaternary semiconductors, defect chalcopyrites, strong methods, nonlinear optical crystals, mid-infrared
With this paper we theoretically investigate the most efficient pump temporal form for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Examination contains fixing the ideal Regulate challenge utilizing the rate equation formalism. The OPO best buildup habits is derived for almost any OPO configuration, and we show that the optimal pump pulse condition is really a double rectangle. The primary rectangle is optimized with the buildup system, when the next a person is optimized with the steady point out, and both equally count in another way about the OPO mirror reflectivities plus the obtainable pump Strength and highest peak electric power.
Tunable mid-IR radiation is acquired in the course of second harmonic era of tunable CO2-laser radiation using a CdGeAs2 crystal. Its angular tuning characteristics within the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
