two–ten.eight-µm wavelength location. Yet another important limitation of your pump power connected having a thermal lensing influence in crystal was firm experimentally. A comparison was product of AgGaSe2 and ZnGeP2 crystals as materials well suited for the productive era of the 2nd harmonic of cw CO2 laser radiation.
We existing new experimental effects to the stage-matching Qualities on the just lately found BaGa2GeSe6
Another software of this setup is seeding superior-stress CO2-laser amplifier [17]. It should be observed that introduced set up in the mid-IR laser system is relatively easy and it has an excellent probable for Strength scalability. Power on the entrance-stop Ti:sapphire laser is often increased as much as a huge selection of Joules [12], however that pump laser will require a wide-aperture BGGSe crystal sample. Also, the DFG pulse Vitality may be enhanced by an enhancement of signal pulse�?uniform spectrum form and increased Electricity.

0 Summary Abstract: BaGa4Se7 (BGSe) and BaGa2GeSe6 (BGGSe) crystals are novel infrared nonlinear optical elements independently created by Chinese researchers. As a result of exceptional detailed general performance as well as the crucial application value in laser industry, they have captivated Substantially awareness at your house and abroad.
The development of crystal progress and laser output of BGSe and BGGSe are summarized, and the longer term advancement is prospected.
77Growth of the new substantial-effectiveness NLO crystal BaGa2GeSe6 via the controlled vapor force system
Laser-induced hurt threshold on the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm during the nanosecond regime
The uniaxial nonlinear crystals BaGa2GeS6 and BaGa2GeSe6 are characterised in terms of thermal diffusivity and precise heat about a temperature number of -ninety to 250 °C for heat propagation together and perpendicular for the c -axis.
It has been found which the optical nonlinear coefficients d31 and d22 in LiNbO3 are of opposite indication, in disagreement with an previously report by Some others. This is a vital thought for optimizing nonlinear optical interactions in LiNbO3.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is really a recently designed nonlinear substance that is appealing for ultrabroad frequency mixing and ultrashort pulse era on account of its comparably very low dispersion and significant destruction threshold. A numerical analyze reveals the fabric’s ability for octave-spanning mid-infrared pulse era around 18 µm. In a first experiment, we show that a lengthy crystal size of 2.
