5 Easy Facts About BaGa2GeSe6 Crystal Described
Blog Article
BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical materials independently produced by Chinese researchers. Due to superb complete functionality along with the critical application worth in laser business, they have captivated A great deal notice in your house and overseas.
2–ten.eight-µm wavelength location. A different critical limitation with the pump energy related that has a thermal lensing result in crystal was determined experimentally. A comparison was made of AgGaSe2 and ZnGeP2 crystals as components suited to the efficient generation of the next harmonic of cw CO2 laser radiation.
spectral range. Moreover, we existing new Sellmeier equations that offer a great replica of your
One more software of the setup is seeding substantial-stress CO2-laser amplifier [seventeen]. It ought to be noted that presented setup of your mid-IR laser program is pretty basic and has an incredible opportunity for Strength scalability. Vitality on the front-conclude Ti:sapphire laser can be greater around many hundreds of Joules [12], having said that that pump laser will require a large-aperture BGGSe crystal sample. Also, the DFG pulse Electrical power can be increased by an improvement of sign pulse�?uniform spectrum form and greater Vitality.

Observe: Author names is going to be searched in the keyword phrases subject, also, but which could obtain papers exactly where the individual is pointed out, instead of website papers they authored.
Intraband magnetotransmission and magnetophotoconductivity ended up calculated approximately 18 T employing CO2 laser traces. The cyclotron resonance and blended resonance harmonics are applied to find out the exchange interaction within an HgMnTe crystal. The experiment also evidences the freezing of electrons from the donor condition. Read through a lot more
77Growth of The brand new large-efficiency NLO crystal BaGa2GeSe6 by using the controlled vapor tension technique
Laser-induced problems threshold on the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm within the nanosecond routine
24% and that is equivalent with just one received with superior repetition charge small-Vitality laser devices like in [nine]. Considering a risk to improve pump pulse Vitality of our setup around ~ten mJ, the DFG pulse Strength is often enhanced around ~24 μJ at precisely the same efficiency, however, it needed a large-aperture, ~15 mm in diameter BGGSe sample. Normal DFG pulse Electricity in AGS wasn't confidently measured with Ophir-3A power meter because of its low signal.
It has been uncovered which the optical nonlinear coefficients d31 and d22 in LiNbO3 are of opposite indication, in disagreement with the before report by others. This is a vital consideration for optimizing nonlinear optical interactions in LiNbO3.
The best frequency conversion performance of ten⁻⁴ was acquired for a relatively new PbIn6Te10 crystal, which is an get of magnitude bigger than former results.
The pump pulse Electrical power was controlled by a variable diffraction attenuator. Its polarization was tuned by ninety° which has a half-wave plate because it had to be regular wave while in the BGGSe (when AGS crystal was applied, the sign beam polarization was tuned). The signal beam was focused by spherical mirror (M2, the focal size of 2 m) into a gas tube of one.
BaGa2GeSe6 crystals are employed for nonlinear optical frequency conversion inside their transparency range. The wavelengths at which utmost conversion efficiencies may be received as well as tuning variety for variance-frequency generation are identified.
