Blog Article
BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical elements independently formulated by Chinese scientists. Because of the great detailed functionality and also the vital application worth in laser market, they may have attracted A lot consideration at your house and overseas.
two–10.eight-µm wavelength area. Another important limitation on the pump ability related which has a thermal lensing result in crystal was firm experimentally. A comparison was product of AgGaSe2 and ZnGeP2 crystals as supplies well suited for the effective era of the second harmonic of cw CO2 laser radiation.

We make superior-get harmonics from crystalline solids employing a tunable mid-IR OPA with fifty kHz repetition rate. Working with nonlinear self-compression in YAG crystals, we make sub 3-cycle pulses at three.eight μm wavelength for high harmonic spectroscopy. Browse a lot more
The dislocations are traced from the repetition of etching from epitaxial layer into the interface. The outcomes clearly show that dislocations during the substrates are expected to bend alongside the direction ordinary towards the epitaxial growth direction within the interface.
A thermo-optic dispersion formula for BaGa2GeSe6 rm BaGa _2 rm GeSe _6 B a G a 2 G e S e six nonlinear crystal is described. The experimentally decided temperature-dependent period-matching circumstances for next-harmonic and sum-frequency technology of Nd:YAG laser-pumped KTiOPO4 rm KTiOPO _4 K T i O P O 4 (KTP) and RbTiOAsO4 rm RbTiOAsO _4 R b T i O A s O four (RTA) optical parametric oscillators in addition to a CO2 rm CO _2 C O 2 laser and its harmonics during the 0.
The progress of crystal development and laser output of BGSe and BGGSe are summarized, and the long run advancement is prospected.
ZnGa2Se4, a nonlinear content with broad mid infrared transparency and excellent thermomechanical Houses

A top quality BGGSe solitary crystal with size of 30 mm×90 mm was grown by Bridgman-stockbarger process, that's the first in China. The prosperous fabrication of BGGSe crystal devices was also attained immediately after orienting, reducing, and sharpening processes, which laid a sound Basis with the additional application investigate with the crystal.
The pertinent Homes and conventions utilized for the recently emerging acentric monoclinic crystals belonging on the borate family members are summarized and tabulated. The derivations are predicted to help you establish adherence to uniform nomenclature and conventions for these novel inorganic nonlinear crystals, and to eradicate ambiguity and escalating confusion in the literature As well as in the industrial specs. The final expressions for the successful nonlinearity are lessened for triclinic crystals of issue team one to simplified varieties during the principal planes.
A not-for-gain Business, IEEE is the earth's major technological Expert Business dedicated to advancing know-how for the good thing about humanity.
The pump pulse Power was managed by a variable diffraction attenuator. Its polarization was tuned by 90° having a 50 %-wave plate since it BaGa2GeSe6 Crystal had to be ordinary wave within the BGGSe (when AGS crystal was used, the signal beam polarization was tuned). The sign beam was centered by spherical mirror (M2, the focal size of 2 m) into a gasoline tube of 1.
