two–10.8-µm wavelength area. Another significant limitation from the pump power linked using a thermal lensing impact in crystal was resolute experimentally. A comparison was made from AgGaSe2 and ZnGeP2 crystals as supplies well suited for the productive technology of the 2nd harmonic of cw CO2 laser radiation.
We existing new experimental effects for your section-matching properties of the not too long ago discovered BaGa2GeSe6

0 Abstract Abstract: BaGa4Se7 (BGSe) and BaGa2GeSe6 (BGGSe) crystals are novel infrared nonlinear optical elements independently formulated by Chinese experts. Because of the superb complete efficiency as well as essential application worth in laser industry, they may have attracted Considerably consideration in your own home and overseas.
Intraband magnetotransmission and magnetophotoconductivity ended up calculated nearly eighteen T using CO2 laser strains. The cyclotron resonance and combined resonance harmonics are used to determine the Trade interaction in an HgMnTe crystal. The experiment also evidences the freezing of electrons from the donor condition. Examine additional
ZnGa2Se4, a nonlinear materials with extensive mid infrared transparency and superior thermomechanical Attributes
Laser-induced damage threshold of your nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm within the nanosecond routine
24% which can be comparable with a single received with high repetition charge minimal-Electrical power laser techniques like in [9]. Making an allowance for a chance to increase pump pulse Electrical power of our setup up to ~ten mJ, the DFG pulse Vitality is often amplified approximately ~24 μJ at the identical efficiency, having said that, it essential a wide-aperture, ~15 mm in diameter BGGSe sample. Average DFG pulse energy in AGS was not confidently measured with Ophir-3A electric power meter because of its small sign.
The habits of dislocations in the interfacial region in between the website epitaxial layer grown with the liquid section and also the substrate of GaAs is investigated. Observations of dislocations lying alongside the 〈one hundred ten�?Instructions were carried out utilizing an optical microscope right after shallow etching using a new chemical etchant.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is really a newly designed nonlinear content that's attractive for ultrabroad frequency mixing and ultrashort pulse generation as a consequence of its comparably lower dispersion and significant harm threshold. A numerical examine reveals the material’s ability for octave-spanning mid-infrared pulse generation as many as eighteen µm. In a primary experiment, we display that a protracted crystal length of 2.
The pump pulse energy was controlled by a variable diffraction attenuator. Its polarization was tuned by 90° by using a half-wave plate as it had to be regular wave during the BGGSe (when AGS crystal was applied, the sign beam polarization was tuned). The sign beam was targeted by spherical mirror (M2, the focal duration of 2 m) into a gas tube of 1.
BaGa2GeSe6 crystals are used for nonlinear optical frequency conversion in their transparency variety. The wavelengths at which most conversion efficiencies is often received along with the tuning selection for difference-frequency generation are discovered.
