5 Simple Techniques For BaGa2GeSe6 Crystal
Blog Article
BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical resources independently created by Chinese researchers. Due to the great complete performance along with the significant software value in laser sector, they've captivated much attention at home and abroad.
two–10.8-µm wavelength area. One more crucial limitation of the pump electricity linked using a thermal lensing impact in crystal was determined experimentally. A comparison was made of AgGaSe2 and ZnGeP2 crystals as resources ideal for the efficient era of the second harmonic of cw CO2 laser radiation.
spectral selection. Also, we existing new Sellmeier equations that offer a superior replica with the
New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) have already been synthesized. The structures of each BaGa2GeS6 and BaGa2GeSe6 were being found to generally be isomorphous exhibiting a three-dimensional framework built through the parallel alignment of Ga or Ge tetrahedron groups alongside the c-aix. The ultraviolet transmittance spectrum implies the limited-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.

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 noted. The experimentally determined temperature-dependent phase-matching conditions for next-harmonic and sum-frequency technology 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 click here s O 4 (RTA) optical parametric oscillators as well as a CO2 rm CO _2 C O 2 laser and its harmonics in the 0.
The progress of crystal progress and laser output of BGSe and BGGSe are summarized, and the longer term advancement is prospected.
ZnGa2Se4, a nonlinear materials with huge mid infrared transparency and great thermomechanical Attributes
Laser-induced hurt threshold of the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm within the nanosecond routine
24% which happens to be comparable with a single acquired with significant repetition level low-Power laser techniques like in [9]. Making an allowance for a possibility to boost pump pulse Vitality of our setup around ~10 mJ, the DFG pulse Vitality could be improved approximately ~24 μJ at precisely the same effectiveness, on the other hand, it expected a wide-aperture, ~fifteen mm in diameter BGGSe sample. Normal DFG pulse Electricity in AGS wasn't confidently measured with Ophir-3A energy meter as a result of its reduced signal.
It's been observed the optical nonlinear coefficients d31 and d22 in LiNbO3 are of opposite sign, in disagreement having an previously report by Other folks. This is an important consideration for optimizing nonlinear optical interactions in LiNbO3.
forty six m duration loaded by CO2 at three atm gas strain where by the laser pulse was broadened due to self-phase modulation below filamentation. Then, the pump and signal pulses had been blended jointly. Enough time correlation with the pump and sign pulses was managed with the pump pulse arm size from the adjustment of mirror M3 situation.
