BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical elements independently formulated by Chinese researchers. As a result of exceptional detailed general performance along with the significant software benefit in laser field, they may have captivated Substantially consideration in your own home and abroad.

spectral range. Moreover, we present new Sellmeier equations that provide a fantastic copy from the
New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) have already been synthesized. The buildings of the two BaGa2GeS6 and BaGa2GeSe6 were located to become isomorphous exhibiting A 3-dimensional framework constructed with the parallel alignment of Ga or Ge tetrahedron teams along 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 make superior-purchase harmonics from crystalline solids utilizing a tunable mid-IR OPA with fifty kHz repetition level. Employing nonlinear self-compression in YAG crystals, we generate sub 3-cycle pulses at 3.eight μm wavelength for top harmonic spectroscopy. Browse much more
To gain usage of this material, remember to total the advice Type and We are going to stick to up along with your librarian or Establishment on your own behalf.
0 Summary Summary: BaGa4Se7 (BGSe) and BaGa2GeSe6 (BGGSe) crystals are novel infrared nonlinear optical components independently formulated by Chinese researchers. Because of the exceptional comprehensive general performance as well as essential application price in laser field, they have got attracted Considerably consideration at home and abroad.
Intraband magnetotransmission and magnetophotoconductivity have been measured approximately 18 T applying CO2 laser strains. The cyclotron resonance and merged resonance harmonics are employed to find out the exchange interaction in an HgMnTe crystal. The experiment also evidences the freezing of electrons from the donor point out. Browse extra

Laser-induced harm threshold from the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm within the nanosecond regime
24% which happens to be equivalent with a person acquired with higher repetition amount very low-energy laser methods like in [9]. Taking into consideration a risk to increase pump pulse energy of our set up as much as ~ten mJ, the DFG pulse Power is usually enhanced as many as ~24 μJ at the same performance, nevertheless, it essential a large-aperture, ~fifteen mm in diameter BGGSe sample. Regular DFG pulse Power in AGS was not confidently calculated with Ophir-3A energy meter due to its low sign.

The very best frequency conversion effectiveness of ten⁻⁴ was acquired for a comparatively new PbIn6Te10 crystal, which can be an purchase of magnitude greater than former outcomes.
The pump pulse energy was controlled by a variable diffraction attenuator. Its polarization was tuned by ninety° that has a 50 percent-wave plate because it needed read more to be ordinary wave during the BGGSe (when AGS crystal was made use of, the sign beam polarization was tuned). The sign beam was targeted by spherical mirror (M2, the focal length of two m) right into a gasoline tube of 1.
The character of this instability and DFG Strength lessen will not be crystal clear for us. Amongst The explanations is often linked that has a nonlinear absorption and plasma development, respectively, that causes reflection/scattering/absorption in the longwave mid-IR pulse. The dependence of BGGSe transmittance on pump pulse Power is presented in Fig.
