BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical supplies independently produced by Chinese experts. Because of the outstanding in depth functionality plus the vital application price in laser industry, they've got attracted Significantly consideration in your own home and overseas.

Numerous courses of IR NLO supplies with outstanding In general efficiency have already been uncovered, for example BaGa4Se7 and BaGa2GeSe6. In addition, the study on these materials has absent over and above crystal framework and preliminary characterization. Terrific efforts have already been performed in the majority crystal growth, within the comprehensive measurement of their physical Attributes employing bulk crystals, during the evaluation in their IR laser output efficiency, and inevitably while in the fabrication of laser system. Inside the frequency down-conversion OPOs pumped by the conventional 1 µm laser, BaGa4Se7 has realized the stable output of mid-considerably IR laser output with the very best power and widest wavelength vary thus far. With this evaluation, rather than masking all compounds with IR NLO properties, our dialogue will only give attention to All those displaying fantastic General IR NLO functionality and software prospect, Specifically on All those of which big sizing single crystals are by now received. This overview then concludes with an outlook on what initiatives can be created Down the road.
We deliver high-order harmonics from crystalline solids using a tunable mid-IR OPA with 50 kHz repetition charge. Applying nonlinear self-compression in YAG crystals, we produce sub three-cycle pulses at 3.eight μm wavelength for top harmonic spectroscopy. Study a lot more

The uniaxial nonlinear crystals BaGa2GeS6 and BaGa2GeSe6 are characterized when it comes to thermal diffusivity and specific warmth above a temperature selection of -ninety to 250 °C for heat propagation together and perpendicular for the c -axis.
The actions of dislocations within the interfacial region in between the epitaxial layer grown from the liquid section as well as substrate of GaAs is investigated. Observations of dislocations lying together the 〈one hundred ten�?directions had been performed applying an optical microscope just after shallow etching which has a new chemical etchant.
The best frequency conversion effectiveness of ten⁻⁴ was received get more info for a relatively new PbIn6Te10 crystal, which is an get of magnitude increased than earlier results.
It's shown there are wavelength combinations at which the effective nonlinearity coefficient may differ only a bit in a wide frequency band.
BaGa2GeSe6 crystals are useful for nonlinear optical frequency conversion inside their transparency assortment. The wavelengths at which maximum conversion efficiencies is often acquired and the tuning array for big difference-frequency era are discovered.
