Optical parametric oscillator pumped at ~one µm with intracavity mid-IR variation-frequency era in OPGaAs
The significance with the obtained benefits lies in the fact that to get the identical conversion in SHG or DFM, just one now necessitates elementary enter radiation with A great deal lower depth.
crystals with ultrafast Yb-ion laser pump is proposed. The outcome type a beneficial reference for the selection of supplies
By applying intracavity dispersion Management, around-change-limited sign pulses of �?a hundred fs length with smooth one-peak spectrum are realized at 1264 nm, akin to an idler wavelength at 6440 nm. To the most effective of our understanding, That is the first time these types of functional idler powers while in the deep-IR happen to be produced from the dispersion-compensated CSP femtosecond OPO at sub-one hundred MHz repetition rate.
We report new experimental effects over the stage-matching Houses of yellow coloration HgGa2S4 crystals for harmonic technology of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers within the 0.944-ten.5910 μm selection. Also, we present new Sellmeier equations that supply a excellent reproduction from the existing experimental success as well as the revealed information points for next-harmonic era of CO2 laser radiation at 9.
This double rectangle is quantitatively described and it is in keeping with prior benefits reported in the literature. Also, numerical simulations are utilized to validate our analytical model with a doubly resonant OPO and demonstrate constant outcomes. The numerical simulations also present that an optimum leading-hat temporal profile could present performances really near the ones achieved Using the ideal double rectangle.
The temperature dependence of refractive indices of optical components is characterized During this get the job done by what we simply call their normalized thermo-optic coefficients. These are generally determined experimentally by means of interferometric measurements of thermal expansion and of variations in optical thickness at some laser wavelengths as perform of temperature. An acceptable vectorial formalism applied to these facts enables predicting the thermal evolution with the refractive index all around the beneficial number of transparency.
air gap and excited in series by a common pump beam. The period with the interference depends on the period shifts at 3 frequencies.

Examination of new, promising extensive-band-hole nonlinear crystals for your mid-IR is specified. We focused on ternary and quaternary chalcogenides and based mostly on their own Actual physical and chemical Qualities, which Besides linear and nonlinear optical properties, decide the effectiveness of crystal usage in certain laser experiments. The correlation among the composition, construction and output parameters and also the traits in changes of the key qualities for example band gap, nonlinear susceptibility, laser injury threshold, etc, are demonstrated.
... The 1st info around the refractive index of orange HGS published by Levine et al. [35] integrated only couple of wavelengths within the noticeable and in close proximity to-IR equally as a demonstration with the feasibility of this crystal for birefringent phase-matching. The refractive indices with the orange period had been calculated and tabulated concerning 0.
twelve μm and describe all frequency conversion strategies realized to this point with them along with future likely purposes. Keywords and phrases: Ternary and quaternary semiconductors, defect chalcopyrites, solid alternatives, nonlinear optical crystals, mid-infrared
The chosen nonlinear crystals show bigger nonlinear conversion performance in comparison to AgGaS 2 , with BaGa two GeS 6 Moreover giving a narrower angular spectrum of spontaneous parametric down conversion, beneficial in interferometric techniques. Our findings build a pathway for integrating Highly developed crystal systems into mid-infrared metrology and imaging devices, placing the stage for future developments in nonlinear interferometry and spectroscopy.
Here is click here the initial example of a broadband OPO operating over the molecular fingerprint location, and we show its probable by conducting broadband Fourier-remodel spectroscopy working with h2o vapor along with a polystyrene reference common.
