BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical components independently created by Chinese scientists. Because of the great complete performance and also the crucial application price in laser field, they have got attracted Significantly attention in your house and abroad.
2–10.8-µm wavelength location. One more crucial limitation with the pump power related by using a thermal lensing result in crystal was firm experimentally. A comparison was crafted from AgGaSe2 and ZnGeP2 crystals as supplies suitable for the productive technology of the next harmonic of cw CO2 laser radiation.
spectral assortment. Moreover, we present new Sellmeier equations that offer a excellent replica in the

A thermo-optic dispersion method for BaGa2GeSe6 rm BaGa _2 rm GeSe _6 B a G a 2 G e S e 6 nonlinear crystal is reported. The experimentally decided temperature-dependent phase-matching conditions for next-harmonic and sum-frequency era of Nd:YAG laser-pumped KTiOPO4 rm KTiOPO _4 K T i O P O four (KTP) and RbTiOAsO4 rm RbTiOAsO _4 R b T i O A s O four (RTA) optical parametric oscillators as well as a CO2 rm CO _2 C O 2 laser and its harmonics in the 0.
Intraband magnetotransmission and magnetophotoconductivity were being calculated up to 18 T utilizing CO2 laser traces. The cyclotron resonance and mixed resonance harmonics are utilised to find out the exchange conversation in an HgMnTe crystal. The experiment also evidences the freezing of electrons in the donor point out. Browse a lot more

Laser-induced injury threshold with the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm in the nanosecond routine
24% that's equivalent with a single attained with large repetition rate low-Electricity laser methods like in [nine]. Considering a chance to extend pump pulse Electricity of our setup up to ~10 mJ, the DFG pulse Strength might be amplified approximately ~24 μJ at the identical efficiency, however, it required a broad-aperture, ~fifteen mm in diameter BGGSe sample. Typical DFG pulse Strength in AGS wasn't confidently measured with Ophir-3A electricity meter due to its very low sign.
The suitable Houses and conventions utilized for the recently emerging acentric monoclinic crystals belonging to your borate loved ones are summarized and tabulated. The derivations are envisioned to help you create adherence to uniform nomenclature and conventions for these novel inorganic nonlinear crystals, also to get rid of ambiguity and expanding confusion in the literature and in the economic specifications. The final expressions for your productive nonlinearity are decreased for triclinic crystals of place group 1 to simplified varieties inside the principal planes.
forty six m size loaded by CO2 at 3 atm fuel tension the place the laser pulse was broadened as a result of self-stage modulation beneath filamentation. Then, the pump and signal pulses were mixed with each other. Some time correlation with the pump and sign pulses was controlled by the pump pulse arm length from the adjustment of mirror M3 posture.
It is actually shown there are wavelength combinations at which the efficient nonlinearity coefficient varies only a little bit in a broad frequency band.
The nature of this instability and DFG Strength decrease is not clear for us. One among the reasons is often relevant having a nonlinear absorption and plasma development, respectively, that triggers reflection/scattering/absorption of the longwave mid-IR pulse. The dependence of BGGSe transmittance on pump pulse energy is introduced in Fig.
