053 μm. The absorption spectrum of ammonia was offered to reveal the feasibility with the created optical parametric oscillator program for spectroscopic measurements and gas detection.
Output idler energies on the microjoule degree are received with utmost conversion effectiveness of eleven% for that amplifier stage, that's a lot more than two times much better than the effects acquired with an analogous sample from the broadly unfold materials AgGaS two .
crystals with ultrafast Yb-ion laser pump is proposed. The outcomes type a practical reference for the choice of products
Research of viable pump laser systems appropriate for ultrafast femtosecond OPOs depending on CdSiP two are mentioned, as well as the favorable linear and nonlinear optical Attributes, in addition to exclusive section-matching qualities of CdSiP two , are offered using The latest Sellmeier equations for the material. The described experimental effects represent the highest output pulse Vitality and report ordinary power in the ultrafast picosecond and femtosecond time scales over the 6–7 μm spectral assortment so far.
Self-referenced octave-huge subharmonic GaP optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
induced oscillations during the idler wavelength of fewer than 200MHz over 300s; the brief-term balance was under 3MHz
Two parametric four-wave-mixing (FWM) processes in Rb atoms are studied making use of perturbation concept underneath the issue of rotating wave approximation. The two parametric FWM procedures are coupled when they're energized coherently by a short laser pulse using a bandwidth encompassing The 2 corresponding upper energy stages in The 2 FWM procedures.
This new version has long been up-to-date and revised to includeimportant developments, ideas and systems that haveemerged Because the publication of the very first edition.
Also, we executed a numerical simulation of chirped-pulse OPOs (CPOPOs) and unveiled that the spectral profile of the output from a CPOPO was relevant to equally the parametric achieve profile in the nonlinear crystal and the intra-cavity higher-get dispersion.
The know-how of growing mercury thiogallate crystals (HgGa2S4) is improved and substantial-high quality bulk samples are created. The essential optical and thermal Houses of those crystals are researched. The transmission spectra of mercury thiogallate are calculated and its nonlinear attributes like the quadratic susceptibility, tuning curves, and also the optical-injury resistance may also be established.
The Digital composition more info and chemical bonding in HgGa2S4 crystals developed by vapor transportation method are investigated with X-ray photoemission spectroscopy. The valence band of HgGa2S4 is found to become formed by splitted S 3p and Hg 6s states at binding energies BE=three 7 eV and the components at BE=7 11 eV produced because of the hybridization of S 3s and Ga 4s states with a powerful contribution from your Hg 5d states. At better binding energies the emission lines linked to the Hg 4f, Ga 3p, S 2p, S 2s, Hg 4d, Ga LMM, Ga 3p and S LMM states are analyzed from the photoemission spectrum.
twelve μm and explain all frequency conversion techniques realized thus far with them and upcoming prospective purposes. Key phrases: Ternary and quaternary semiconductors, defect chalcopyrites, good options, nonlinear optical crystals, mid-infrared
Mid-IR second-get NLO crystal is indispensable inside the frequency conversion purposes from the mid-IR region. In contrast with DUV and UV/Vis/in close proximity to-IR NLO crystals, realistic mid-IR NLO crystals are comparatively uncommon, and lots of of these are still in the phase of laboratory analysis. This chapter reviews the the latest progress over the mid-IR NLO crystals, which largely contains rising the classical mid-IR NLO crystals into substantial substantial-top quality ones or into quasi-phase-matching constructions that are suitable for the laser devices by different advancement solutions and exploring new prospective mid-IR NLO crystals by introducing new style and design and synthesis techniques.
three% rms above 12 h in good beam high quality. The close to-IR sign pulses with the OPO Use a Gaussian pulse duration of �?19 ps , calculated at 1284 nm. We've investigated the temperature tuning characteristics of your OPO and when compared the data With all the theoretical calculations employing The newest Sellmeier equations and thermo-optic coefficients to the crystal. To the top of our knowledge, this is the to start with picosecond OPO based on CSP functioning at MHz repetition fees.
