We report new experimental benefits about the phase-matching Homes of the BaGa4Se7 crystal for harmonic era of the Nd:YAG laser-pumped AgGaS2 optical parametric oscillator (OPO) and also a CO2 laser…
The deforming vibrations of Ga–O–Ga bonds while in the defect crystal develop two IR absorption bands Situated all-around 665 cm−one, akin to the crystal residual absorption. The end result may help us to get rid of the residual absorption and improve the crystal excellent.

A ongoing-wave mid-infrared radiation from variation frequency generation by mixing a steady-wave Ti: sapphire laser as well as a steady-wave YAG laser in the 15 mm very long BaGa4Se7 crystal is…

The BaGa4Se7 (BGSe) crystal is an excellent mid- and much-IR nonlinear optical crystal, but normally demonstrates an unpredicted residual absorption peak all-around fifteen μm which substantially deteriorates the crystal general performance. The structural origin of residual absorption remains to be under discussion.
′�?, with a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−one phonon corresponds to your crystal IR absorption edge, in lieu of the residual absorption peak. Density purposeful idea computations clearly show that the residual absorption in the BGSe click here crystal originates through the OSe defect (Se is substituted by O).
