BaGa2GeSe6 Crystal - An Overview
Blog Article
BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical resources independently designed by Chinese scientists. Due to great thorough functionality as well as the essential software value in laser market, they have attracted A great deal awareness in your own home and abroad.
two–10.eight-µm wavelength region. A different crucial limitation of the pump electric power connected which has a thermal lensing influence in crystal was firm experimentally. A comparison was manufactured from AgGaSe2 and ZnGeP2 crystals as elements well suited for the efficient generation of the second harmonic of cw CO2 laser radiation.

Another application of this set up is seeding higher-stress CO2-laser amplifier [17]. It ought to be pointed out that presented setup of your mid-IR laser technique is comparatively very simple and it has a great potential for Strength scalability. Vitality in the front-stop Ti:sapphire laser can be elevated up to numerous Joules [12], however that pump laser would require a wide-aperture BGGSe crystal sample. Also, the DFG pulse Power can be enhanced by an advancement of signal pulse�?uniform spectrum condition and amplified energy.

The dislocations are traced with the repetition of etching from epitaxial layer towards the interface. The effects show that dislocations inside the substrates are predicted to bend alongside the way regular to your epitaxial growth route within the interface.
0 Summary Abstract: BaGa4Se7 (BGSe) and BaGa2GeSe6 (BGGSe) crystals are novel infrared nonlinear optical resources independently developed by Chinese scientists. As a result of superb in depth effectiveness as well as the important software value in laser marketplace, they have attracted A great deal interest at your house and overseas.
The progress of crystal progress and laser output of BGSe and BGGSe are summarized, and the long run improvement is prospected.
ZnGa2Se4, a nonlinear content with extensive mid infrared transparency and good thermomechanical Homes
Join ResearchGate to find out and not sleep-to-day with the most up-to-date investigation from major industry experts in CO2 Laser and all kinds of other scientific subjects.
The uniaxial nonlinear crystals BaGa2GeS6 and BaGa2GeSe6 are characterised with regard to thermal diffusivity and distinct heat in excess of a temperature selection of -90 to 250 °C for heat propagation along and perpendicular towards the c -axis.
It's been located that the optical nonlinear coefficients d31 and d22 in LiNbO3 are of reverse indication, in disagreement with the previously report by Some others. This is a crucial consideration for optimizing nonlinear optical interactions in LiNbO3.
forty six m size crammed by CO2 at 3 atm gas strain the place the laser pulse was broadened resulting from self-phase modulation underneath filamentation. Then, the pump and signal pulses were being mixed alongside one another. Some time correlation in the pump and signal pulses was managed because of the pump pulse arm duration from the adjustment of mirror M3 situation.
The pump pulse Electrical power was managed by a variable diffraction attenuator. Its polarization was tuned by 90° which has a half-wave plate since it had to be standard wave from the BGGSe (when AGS crystal was made use of, the signal beam polarization was tuned). The signal beam was concentrated by spherical mirror (M2, the focal size of two m) right more info into a gasoline tube of 1.
The nature of this instability and DFG Vitality reduce just isn't obvious for us. Among The explanations is often connected with a nonlinear absorption and plasma formation, respectively, that triggers reflection/scattering/absorption of the longwave mid-IR pulse. The dependence of BGGSe transmittance on pump pulse Power is presented in Fig.
