Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variance-frequency technology in OPGaAs

Output idler energies around the microjoule amount are acquired with most conversion effectiveness of 11% for that amplifier stage, and that is a lot more than two occasions much better than the outcome attained with the analogous sample of your broadly spread content AgGaS two .

crystals with ultrafast Yb-ion laser pump is proposed. The results form a helpful reference for the selection of components

By applying intracavity dispersion Handle, near-completely transform-minimal signal pulses of �?one hundred fs duration with clean solitary-peak spectrum are realized at 1264 nm, equivalent to an idler wavelength at 6440 nm. To the best of our knowledge, this is The very first time this kind of useful idler powers in the deep-IR are produced from a dispersion-compensated CSP femtosecond OPO at sub-100 MHz repetition price.

in the laser emission wavelength. The bare minimum calculated qualifications signal on the PA sensor (working with substantial purity

The high conversion performance and wide selection of radiation wavelength tuning allows to assume this substance may perhaps compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Regardless of the sizeable issue of massive measurement crystals growth approach.

The temperature dependence of refractive indices of optical components is characterized With this work by what we get in touch with their normalized thermo-optic coefficients. These are generally identified experimentally through interferometric measurements of thermal expansion and of improvements in optical thickness at a handful of laser wavelengths as functionality of temperature. A suitable vectorial formalism applied to these information permits predicting the thermal evolution of your refractive index all over the useful variety of transparency.

This re-creation has been up-to-date and revised to includeimportant developments, ideas and systems that haveemerged since the publication of the first version.

Reliable condition polymerization of diacetylenes The crystal structure of HAlSi2O6 which has a keatite-form framework Syntheses and crystal constructions of α

The technology of increasing mercury thiogallate crystals (HgGa2S4) is enhanced and superior-top quality bulk samples are created. The essential optical and thermal properties of such crystals are examined. The transmission spectra of mercury thiogallate are measured and its nonlinear features such as the quadratic susceptibility, tuning curves, as well as the optical-harm resistance may also be determined.

The defect chalcopyrite crystal HgGa2S4 has become utilized in the 1064-nm pumped optical parametric oscillator to create Nonlinear crystals for optical parametric oscillators pumped by mild pulses of close to IR lasers...

twelve μm and describe all frequency conversion strategies realized to date with them and potential probable applications. Key phrases: Ternary and quaternary semiconductors, defect chalcopyrites, stable remedies, nonlinear optical crystals, mid-infrared

The chosen nonlinear crystals show bigger nonlinear conversion efficiency when compared with AgGaS 2 , with BaGa 2 GeS 6 On top of that providing a narrower angular spectrum of more info spontaneous parametric down conversion, beneficial in interferometric techniques. Our results set up a pathway for integrating Innovative crystal systems into mid-infrared metrology and imaging units, placing the phase for long term developments in nonlinear interferometry and spectroscopy.

This is actually the initially illustration of a broadband OPO functioning across the molecular fingerprint region, and we show its prospective by conducting broadband Fourier-rework spectroscopy applying h2o vapor and a polystyrene reference conventional.
