.. [Present complete abstract] third-harmonic generation and parametric amplification with minimal-frequency pumping in periodically poled Lively nonlinear crystals are investigated. The Examination is performed for the case of the periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of using periodically poled Lively nonlinear crystals in laser equipment with self-frequency conversion are talked over.
Self-referenced octave-huge subharmonic GaP optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
The measured Main amount binding energies are in comparison with those of HgS, Gasoline, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves to be unbiased within the technological disorders of crystal advancement. In contrast on the valence band spectrum, the distribution of electron states during the bandgap of HgGa2S4 crystals is observed to become strongly dependent upon the technological situations of crystal growth as demonstrated through the photoluminescence analysis.

The electronic construction and chemical bonding in HgGa2S4 crystals grown by vapor transportation method are investigated with X-ray photoemission spectroscopy. The valence band of HgGa2S4 is uncovered to be formed by splitted S 3p and Hg 6s states at binding energies BE=3 7 eV as well as components at BE=seven eleven eV produced via the hybridization of S 3s and Ga 4s states with a solid contribution with the Hg 5d states. At better binding energies the emission strains connected with the Hg 4f, Ga 3p, S 2p, S 2s, Hg 4d, Ga LMM, Ga 3p and S LMM states are analyzed inside the photoemission spectrum.
The noticed file -to- two f frequency beats, originating straight from the OPO, can be utilized for self-referencing and phase locking of your pump laser comb without having for supercontinuum technology. With a median output electricity of �?30 mW , this set up could be advantageous for a range of spectroscopic programs inside the mid-IR.
Solitary-stage sub-two hundred fs mid-infrared era from an optical parametric oscillator synchronously pumped by an erbium fiber laser
three% rms more than 12 h in very good beam high-quality. The near-IR signal pulses with the OPO Have got a read more Gaussian pulse duration of �?19 ps , calculated at 1284 nm. We have now investigated the temperature tuning properties in the OPO and in comparison the info Together with the theoretical calculations making use of The latest Sellmeier equations and thermo-optic coefficients to the crystal. To the most effective of our information, This can be the very first picosecond OPO based upon CSP functioning at MHz repetition prices.
