Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR change-frequency technology in OPGaAs
The significance in the received results lies in The reality that to have the same conversion in SHG or DFM, a single now demands essential input radiation with A great deal decreased intensity.

By applying intracavity dispersion control, around-transform-minimal sign pulses of �?one hundred fs period with sleek single-peak spectrum are reached at 1264 nm, corresponding to an idler wavelength at 6440 nm. To the most beneficial of our understanding, This is often the first time these kinds of practical idler powers within the deep-IR are produced from a dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition charge.
We report new experimental results on the section-matching Houses of yellow colour HgGa2S4 crystals for harmonic technology of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers inside the 0.944-10.5910 μm selection. Furthermore, we present new Sellmeier equations that offer a very good reproduction with the present experimental outcomes plus the published facts points for 2nd-harmonic era of CO2 laser radiation at nine.
The measured core amount binding energies are compared with These of HgS, GaS, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves for being impartial within the technological problems of crystal progress. In distinction on the valence band spectrum, the distribution of electron states while in the bandgap of HgGa2S4 crystals is located to get strongly dependent upon the technological conditions of crystal advancement as demonstrated via the photoluminescence Investigation.
Two parametric four-wave-mixing (FWM) procedures in Rb atoms are studied using perturbation concept under the problem of rotating wave approximation. The two parametric FWM processes are coupled when they're excited coherently by a short laser pulse having a bandwidth encompassing The 2 corresponding upper energy degrees in the two FWM procedures.
Pumping mid-IR optical parametric oscillators near one μm is click here beautiful for its simplicity and power scaling ability. To this aim, extensive bandgap non-oxide nonlinear crystals are necessary.
Vibrational spectra of Li-containing nonlinear crystals and their software in THz radiation technology are mentioned. Working with an illustration of LiGaS2, the defect effect on spectroscopic qualities is demonstrated. Superior-temperature annealing in a proper ambiance will allow 1 to get rid of extended and place defects also to Increase the transparency. Electrical power composition and parameters of main point defects like anion vacancy (F-center) and cation antisite defect GaLi calculated from the very first principles agree nicely Using the experimental final results.
Evaluation of latest, promising wide-band-hole nonlinear crystals for the mid-IR is presented. We focused on ternary and quaternary chalcogenides and dependent on their own physical and chemical Homes, which Besides linear and nonlinear optical properties, establish the performance of crystal use in specific laser experiments. The correlation involving the composition, composition and output parameters in addition to the tendencies in changes of the primary attributes which include band hole, nonlinear susceptibility, laser damage threshold, and so on, are demonstrated.
Interference is observed in between the spontaneous parametric radiation from two nonlinear crystals divided by a macroscopic
twelve μm and explain all frequency conversion schemes realized up to now with them and also long term probable purposes. Keywords and phrases: Ternary and quaternary semiconductors, defect chalcopyrites, stable alternatives, nonlinear optical crystals, mid-infrared
Solitary-stage sub-200 fs mid-infrared technology from an optical parametric oscillator synchronously pumped by an erbium fiber laser
Diode-pumped optical parametric oscillation has actually been shown for The very first time to our know-how in an individual Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions take up the 812-nm radiation to crank out 1084-nm laser oscillation.
