BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical elements independently made by Chinese experts. Due to fantastic comprehensive overall performance as well as the essential software benefit in laser field, they've got attracted Considerably awareness in the home and abroad.

New middle infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) are actually synthesized. The constructions of equally BaGa2GeS6 and BaGa2GeSe6 were being found to be isomorphous exhibiting A 3-dimensional framework produced via the parallel alignment of Ga or Ge tetrahedron groups together the c-aix. The ultraviolet transmittance spectrum suggests the brief-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
We deliver significant-purchase harmonics from crystalline solids utilizing a tunable mid-IR OPA with fifty kHz repetition price. Working with nonlinear self-compression in YAG crystals, we produce sub 3-cycle pulses at 3.eight μm wavelength for high harmonic spectroscopy. Study additional
The dislocations are traced via the repetition of etching from epitaxial layer to the interface. The results display that dislocations while in the substrates are expected to bend alongside the path ordinary to the epitaxial development course for the interface.
Note: Writer names will probably be searched while in the keyword phrases area, also, but that will discover papers where by the individual is mentioned, instead of papers they authored.
Even though utilizing an institutional account for this Web page we don’t track any personalized, effectiveness, practical or 1st or 3rd party connected info.
ZnGa2Se4, a nonlinear substance with extensive mid infrared transparency and good thermomechanical Houses
Nonlinear optical (NLO) crystals can change the frequencies of existing lasers to other favorable wavelength ranges, and they are hence critical content basis of photoelectron technological know-how. At present, There's an urgent require to investigate new NLO elements inside the deep UV and IR array. On this evaluation, we deal with the latest progress on new IR NLO elements with software prospect. The primary obstacle of getting new pretty much usable IR NLO crystals will be to synthesize new supplies which can accomplish the coexistence of various fascinating Homes which includes sufficient SHG coefficients, large mid-far IR transparency variety, large laser injury threshold, moderate birefringence, favorable single-crystal progress behavior, and secure physicochemical Homes. Here, we spotlight the analysis method combining “structural style�?with “exploratory synthesis�?can considerably improve the efficiency of pinpointing new practical IR NLO components in metal chalcogenides.
24% that's comparable with one particular acquired with superior repetition price lower-energy laser systems like in [9]. Making an allowance for a probability to boost pump pulse energy of our setup nearly ~10 mJ, the DFG pulse Electricity is usually increased as many as ~24 μJ at exactly the same efficiency, even so, it expected a large-aperture, ~15 mm in diameter BGGSe sample. Common DFG pulse Strength in AGS was not confidently calculated with Ophir-3A electrical power meter on account of its reduced sign.
A thermo-optic dispersion method for BaGa2GeSe6 rm BaGa _2 rm GeSe _6 B a G a two G e S e 6 nonlinear crystal is reported. The experimentally decided temperature-dependent phase-matching problems for second-harmonic and sum-frequency generation of Nd:YAG laser-pumped KTiOPO4 rm KTiOPO _4 K T i O P O four (KTP) and RbTiOAsO4 rm RbTiOAsO _4 R b T i O A s O 4 (RTA) optical parametric oscillators in addition to a CO2 rm CO _2 C O 2 laser and its harmonics inside the 0.
The very best frequency conversion effectiveness of 10⁻⁴ was acquired for a relatively new PbIn6Te10 crystal, which can be an order of magnitude better than preceding benefits.
The pump pulse Electrical power was managed by a variable diffraction attenuator. Its polarization was tuned by ninety° which has a fifty percent-wave plate since it had to be regular wave in the BGGSe (when AGS crystal was used, the sign beam polarization was tuned). The sign beam was targeted by spherical mirror (M2, the focal size of two m) into a gas tube of 1.
BaGa2GeSe6 crystals are employed for nonlinear optical frequency conversion of their transparency assortment. The wavelengths at which utmost conversion here efficiencies could be attained and the tuning array for change-frequency technology are uncovered.
