0 Summary Abstract: BaGa4Se7 (BGSe) and BaGa2GeSe6 (BGGSe) crystals are novel infrared nonlinear optical supplies independently made by Chinese researchers. Because of the fantastic thorough overall performance as well as significant application worth in laser marketplace, they've attracted A great deal interest at your house and abroad.
Whilst using an institutional account for this Web site we don’t keep track of any own, performance, purposeful or 1st or 3rd occasion linked data.
Over the last a long time, mid-infrared (3–twelve μm) laser sources working with crystals with nonlinear optical Houses have captivated a specific awareness because of their likely programs in numerous read more fields including optical counter-measures and distant chemical sensing. As transparency of typical oxide crystals is limited to about four μm, several researches happen to be focused on chalcopyrite compounds thanks to their broad transparency inside the mid-IR range and their strong nonlinear optical coefficients. You will find there's need to have of such crystals capable to transform efficiently the close to infrared wavelengths from commercially available lasers into wavelengths bigger than five μm as a result of Optical Parametric Oscillators (OPO) techniques.

The highest frequency conversion effectiveness of ten⁻⁴ was obtained for a relatively new PbIn6Te10 crystal, which can be an purchase of magnitude larger than preceding results.
It's proven that there are wavelength combinations at which the efficient nonlinearity coefficient varies only slightly in a broad frequency band.
