Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variation-frequency era in OPGaAs
Output idler energies over the microjoule stage are acquired with most conversion performance of 11% to the amplifier stage, which happens to be more than two situations much better than the outcomes attained having an analogous sample of the broadly unfold content AgGaS two .
crystals with ultrafast Yb-ion laser pump is proposed. The effects kind a beneficial reference for the choice of elements
By implementing intracavity dispersion Regulate, close to-renovate-minimal sign pulses of �?100 fs period with smooth one-peak spectrum are accomplished at 1264 nm, akin to an idler wavelength at 6440 nm. To the top of our awareness, This is certainly the first time these kinds of sensible idler powers from the deep-IR are generated from the dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition fee.
A laser fuel analyzer continues to be suitable for identifying the composition of exhaled air through photoacoustic spectroscopy. The analyzer, depending on a broadband optical parametric oscillator and photoacoustic detector, delivers high-precision speedy Examination in the multicomponent composition of human exhaled air for dynamic estimation on the effectiveness of treating bronchus and lung health conditions.
brought about oscillations inside the idler wavelength of below 200MHz above 300s; the shorter-phrase steadiness was under 3MHz
The temperature dependence of refractive indices of optical elements is characterised On this do the job by what we simply call their normalized thermo-optic coefficients. They're decided experimentally by way of interferometric measurements of thermal expansion and of adjustments in optical thickness at some laser wavelengths as purpose of temperature. An acceptable vectorial formalism applied to these info will allow predicting the thermal evolution from the refractive index all around the helpful selection of transparency.
Determined by the theories of phase matching and acceptable composition ratio, the affect of composition ratio on the frequency conversions of two forms (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In consideration of corresponding sellmeier equations, phase matching diagrams of next harmonic generation and optical parametric oscillations pumped by the favored Nd3+:YAG and Ho3+:YLF lasers ended up calculated, together with suitable composition ratios with different compositions.
The particular heat and thermal conductivity of HgGa2S4 are calculated. It can be concluded the blended properties of HgGa2S4 crystals can offer for them a number one posture among the components Employed in nonlinear-optical products for mid-IR-frequency conversion.
Topics could be refined even more while in the search results. The subject side will expose the higher-level subjects affiliated with the article content returned from the search results. SPECIAL COLLECTIONS
... The first knowledge on the refractive index of orange HGS posted by Levine et al. [35] integrated only handful of wavelengths while in the obvious and close to-IR just as a demonstration in the feasibility of this crystal for birefringent stage-matching. The refractive indices to the orange period have been calculated and tabulated involving 0.
We report a broadband optical parametric oscillator (OPO) more info pumped by a Yb-doped fiber laser system. By using a 300 μm prolonged magnesium-doped periodically poled LiNbO 3 crystal given that the parametric acquire medium and configuring the OPO to be a chirped-pulse oscillator, we received mid-infrared emission having an instantaneous bandwidth covering 3084�?466 nm. This result represents, to the very best of our expertise, the widest instantaneous bandwidth acquired from the Yb-fiber-laser-pumped singly resonant OPO, demonstrating the huge prospective of chirped-pulse oscillation in scaling the instantaneous bandwidth of ultra-fast OPOs.
With this paper we theoretically investigate one of the most effective pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical analysis consists of fixing the ideal Command problem using the charge equation formalism. The OPO optimal buildup habits is derived for almost any OPO configuration, and we exhibit that the optimum pump pulse form can be a double rectangle. The 1st rectangle is optimized for your buildup course of action, even though the second a person is optimized with the constant point out, and both equally count in different ways on the OPO mirror reflectivities along with the readily available pump Electricity and highest peak power.
This can be the initially example of a broadband OPO operating through the molecular fingerprint region, and we show its probable by conducting broadband Fourier-rework spectroscopy using h2o vapor plus a polystyrene reference typical.
