A Simple Key For BaGa2GeSe6 Crystal Unveiled
Blog Article
BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical elements independently produced by Chinese scientists. As a result of exceptional extensive overall performance plus the crucial application price in laser sector, they have got captivated Considerably consideration at home and abroad.
To achieve entry to this articles, you should total the advice Form and we will comply with up with your librarian or Establishment in your behalf.
We present new experimental success for that period-matching Houses of your just lately discovered BaGa2GeSe6
New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) are actually synthesized. The structures of equally BaGa2GeS6 and BaGa2GeSe6 ended up uncovered to get isomorphous exhibiting a three-dimensional framework made via the parallel alignment of Ga or Ge tetrahedron groups together the c-aix. The ultraviolet transmittance spectrum implies the small-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.

New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) are already synthesized. The buildings of each BaGa2GeS6 and BaGa2GeSe6 were being uncovered being isomorphous exhibiting A 3-dimensional framework made from the parallel alignment of Ga or Ge tetrahedron teams alongside the c-aix. The ultraviolet transmittance spectrum indicates the shorter-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
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 reported. The experimentally determined temperature-dependent phase-matching ailments for next-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 four (RTA) optical parametric oscillators in addition to a CO2 rm CO _2 C O two laser and its harmonics in the 0.
The progress of crystal progress and laser output of BGSe and BGGSe are summarized, and the future enhancement is prospected.

Distinctive emphasis might be presented to The present technological limitations and availability of pump laser traits and nonlinear crystal properties. Go through a lot more
The conduct of dislocations in the interfacial location concerning the epitaxial layer developed from the liquid stage as well as the substrate of GaAs is investigated. Observations of dislocations lying alongside the 〈one hundred ten�?Instructions ended up completed utilizing an optical microscope soon after shallow etching having a new chemical etchant.
A not-for-income Group, IEEE is the earth's major technological Experienced Firm focused on advancing engineering for the website advantage of humanity.
The pump pulse energy was managed by a variable diffraction attenuator. Its polarization was tuned by 90° by using a fifty percent-wave plate since it needed to be ordinary wave from the BGGSe (when AGS crystal was used, the signal beam polarization was tuned). The sign beam was focused by spherical mirror (M2, the focal size of two m) right into a fuel tube of 1.
BaGa2GeSe6 crystals are useful for nonlinear optical frequency conversion within their transparency vary. The wavelengths at which greatest conversion efficiencies may be received as well as the tuning array for distinction-frequency generation are located.
