Blog Article
BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical components independently produced by Chinese scientists. Because of the great in depth overall performance along with the vital software worth in laser market, they've got captivated Significantly notice in your own home and overseas.

We current new experimental results for the section-matching Attributes from the not long ago uncovered BaGa2GeSe6
New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) have already been synthesized. The structures of the two BaGa2GeS6 and BaGa2GeSe6 have been discovered to become isomorphous exhibiting a three-dimensional framework created via the parallel alignment of Ga or Ge tetrahedron teams alongside the c-aix. The ultraviolet transmittance spectrum implies the quick-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.

The highest frequency conversion efficiency of 10⁻⁴ was received for a comparatively new PbIn6Te10 crystal, that is an buy of magnitude bigger than prior benefits.
The pump pulse Vitality was controlled by a variable diffraction attenuator. Its polarization was tuned by ninety° by using a fifty percent-wave plate since it needed to be common wave in the BGGSe (when AGS crystal was used, the sign beam polarization was tuned). The signal beam was focused by spherical mirror (M2, the focal duration of two m) into a fuel tube of one.
BaGa2GeSe6 crystals are employed for nonlinear optical frequency conversion read more of their transparency range. The wavelengths at which optimum conversion efficiencies might be acquired along with the tuning assortment for variation-frequency technology are observed.
