BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical resources independently developed by Chinese scientists. Due to the superb thorough performance plus the critical software benefit in laser market, they have got captivated Substantially awareness in the home and overseas.
2–ten.eight-µm wavelength area. Another vital limitation with the pump energy linked with a thermal lensing result in crystal was firm experimentally. A comparison was made of AgGaSe2 and ZnGeP2 crystals as resources suited to the productive era of the next harmonic of cw CO2 laser radiation.
We existing new experimental success for the section-matching Attributes from the a short while ago found out BaGa2GeSe6

0 Summary Abstract: BaGa4Se7 (BGSe) and BaGa2GeSe6 (BGGSe) crystals are novel infrared nonlinear optical components independently produced by Chinese experts. Due to the excellent extensive overall performance and the important software worth in laser market, they have captivated Considerably consideration in the home and overseas.

24% that's comparable with one particular acquired with high repetition more info rate low-Electricity laser systems like in [9]. Making an allowance for a possibility to increase pump pulse Electricity of our setup as many as ~10 mJ, the DFG pulse Electricity can be greater as many as ~24 μJ at the same effectiveness, even so, it needed a large-aperture, ~15 mm in diameter BGGSe sample. Normal DFG pulse energy in AGS wasn't confidently calculated with Ophir-3A energy meter because of its very low signal.

$ rm BaGa _2 rm GeSe _6$ (BGGSe) is often a newly developed nonlinear material which is interesting for ultrabroad frequency mixing and ultrashort pulse generation as a consequence of its comparably very low dispersion and substantial harm threshold. A numerical analyze shows the fabric’s capacity for octave-spanning mid-infrared pulse technology up to eighteen µm. In a first experiment, we show that an extended crystal length of two.

BaGa2GeSe6 crystals are employed for nonlinear optical frequency conversion inside their transparency array. The wavelengths at which maximum conversion efficiencies is often attained as well as tuning range for change-frequency generation are discovered.
