BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical elements independently formulated by Chinese scientists. As a result of excellent thorough functionality as well as the essential software price in laser field, they have captivated Considerably notice in your own home and overseas.

New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) have already been synthesized. The structures of equally BaGa2GeS6 and BaGa2GeSe6 were discovered to be isomorphous exhibiting a three-dimensional framework built through 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.

Be aware: Author names is going to be searched within the key phrases subject, also, but that may obtain papers where by the individual is mentioned, rather then papers they authored.

The development of crystal expansion and laser output of BGSe and BGGSe are summarized, and the longer term enhancement is prospected.

Laser-induced damage threshold of your nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm during the nanosecond regime

A top quality BGGSe single crystal with sizing of thirty mm×90 mm was developed by Bridgman-stockbarger system, which can be the very first in China. The prosperous fabrication of BGGSe crystal gadgets was also accomplished right after orienting, cutting, and polishing processes, which laid a stable Basis with the even further software exploration in the crystal.

The behavior of dislocations while in the interfacial region among the epitaxial layer developed from the liquid stage as well as substrate of GaAs is investigated. Observations of dislocations lying along the 〈one hundred ten�?Instructions were completed working with an optical microscope after shallow etching using a new chemical etchant.

forty six m duration loaded by CO2 at three atm fuel pressure in which the laser pulse was broadened on account of self-period modulation underneath filamentation. Then, the pump and sign pulses were being combined with each other. Enough time correlation in the pump and sign pulses was managed from the pump pulse arm length with the adjustment of mirror M3 place.

It really is shown that there are wavelength combos at which the helpful nonlinearity coefficient varies BaGa2GeSe6 Crystal only a little in a large frequency band.

The nature of this instability and DFG Vitality lessen isn't very clear for us. Amongst the reasons is usually connected by using a nonlinear absorption and plasma formation, respectively, that causes reflection/scattering/absorption in the longwave mid-IR pulse. The dependence of BGGSe transmittance on pump pulse Electrical power is presented in Fig.
