With the advent of recent nonlinear resources and solitary-frequency pump resources, There exists renewed fascination in optical parametric oscillators (OPOs). Just one-manner diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is both equally amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
Output idler energies on the microjoule degree are obtained with most conversion effectiveness of 11% with the amplifier phase, which is in excess of two moments better than the effects received by having an analogous sample in the greatly spread substance AgGaS 2 .

.. [Clearly show full abstract] third-harmonic era and parametric amplification with very low-frequency pumping in periodically poled Energetic nonlinear crystals are investigated. The analysis is carried out for the case of a periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of using periodically poled Lively nonlinear crystals in laser equipment with self-frequency conversion are discussed.
A laser gasoline analyzer has long been made for analyzing the composition of exhaled air by way of photoacoustic spectroscopy. The analyzer, based upon a broadband optical parametric oscillator and photoacoustic detector, gives superior-precision fast Investigation of the multicomponent composition of human exhaled air for dynamic estimation on the performance of managing bronchus and lung ailments.
The measured core level binding energies are as opposed with People of HgS, Fuel, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves to become impartial over the technological conditions of crystal expansion. In distinction to your valence band spectrum, the distribution of electron states inside the bandgap of HgGa2S4 crystals is located to get strongly dependent on the technological situations of crystal expansion as shown with the photoluminescence analysis.
Two parametric four-wave-mixing (FWM) procedures in Rb atoms are researched applying perturbation concept underneath the ailment of rotating wave approximation. The 2 parametric FWM procedures are coupled when they're enthusiastic coherently by a short laser pulse by using a bandwidth encompassing the two corresponding upper energy levels in The 2 FWM procedures.
We present a numerical research for the look of productive MgO:PPLN centered pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of prime-hat transverse intensity profile, as well as a double-move pump cavity configuration. Particularly, we look into the result of area shape about the conversion performance. We viewed as two varieties of domain constructions: "best vertical-wall" and "wedge-formed" domains and our numerical success exhibit that at bigger pump pulse energies, the conversion more info efficiency saturates, as well as saturated effectiveness is almost unbiased from the domain designs.

The technological innovation of rising mercury thiogallate crystals (HgGa2S4) is enhanced and large-high quality bulk samples are produced. The essential optical and thermal Homes of these crystals are analyzed. The transmission spectra of mercury thiogallate are measured and its nonlinear properties like the quadratic susceptibility, tuning curves, as well as optical-hurt resistance can also be identified.
... The 1st knowledge to the refractive index of orange HGS released by Levine et al. [35] incorporated only couple of wavelengths while in the visible and close to-IR equally as an illustration on the feasibility of this crystal for birefringent phase-matching. The refractive indices for that orange stage were calculated and tabulated between 0.
Note: Writer names will probably be searched from the search phrases field, also, but which could find papers the place the person is pointed out, rather than papers they authored.
The selected nonlinear crystals show increased nonlinear conversion efficiency in comparison to AgGaS two , with BaGa 2 GeS 6 Moreover presenting a narrower angular spectrum of spontaneous parametric down conversion, beneficial in interferometric techniques. Our results build a pathway for integrating Innovative crystal systems into mid-infrared metrology and imaging programs, environment the phase for long term developments in nonlinear interferometry and spectroscopy.
Diode-pumped optical parametric oscillation continues to be demonstrated for The 1st time to our awareness in one Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions take in the 812-nm radiation to make 1084-nm laser oscillation.
