5 Simple Statements About AgGaSe2 Crystal Explained
Blog Article
Defect-associated absorption and luminescence were being disclosed and a means to reduced them was suggested. The Digital structure, density of states, plus some optical Homes were calculated from the main rules for Li2In2GeSe6. Calculated nonlinear coefficients and fairly large birefringence point out a strong period-matching ability. These investigations exhibit that Li2In2GeSe6 is usually a promising mid-infrared nonlinear optical crystal.

The usage of a LiTaO(three) retarder is proposed to attain an orthogonal state of polarization involving OPO outputs which might be necessary for successful pumping of the AgGaSe(2) crystal.
Li0.78Ag0.22InSe2 crystal is grown via the modified Bridgman−Stockbarger technique, and it exhibits a wide

Typically, not all responses to the above thoughts are "Of course", so you have to stike a balance between these aspects to discover the finest Option on your methods. Such as, to secure a SHG crystal for Ti:Sapphire laser at 800nm, with the heart beat width of 40fs, and also the envisioned pulse broadening outcome fewer than 20fs. KTP, AgGaSe2 or AgGaS2 can't realize section matching of SHG800nm; LiIO3's hurt threshold is just not substantial more than enough; Both of those BBO and KDP are suited, having said that, BBO's conversion effieicy is better than KDP, and 100micron BBO SHG800nm can only generate pulse broadening influence of 19fs.
Good quality AgGaSe2 one crystals with twenty mm in diameter and fifty five mm in duration have been developed by Bridgman technique. It is uncovered that there is a next period of Ag-prosperous Ga2Se3 (or named AgGa7Se11) from the AgGaSe2 crystal.

The substitution of 50 percent on the weighty Ag�?cations with mild Li�?raises the band gap to two.2 eV (vs. one.seven eV in AgGaSe2). The LDT price in AgLiGa2Se4 will increase 5 times compared to that in AgGaSe2, while preserving AgGaSe2 Crystal a relatively significant NLO susceptibility of 26 pm V⁻�? Furthermore, the thermal enlargement coefficients in AgLiGa2Se4 are about two times lessen in absolute value when compared with AgGaSe2, which is useful to the large crystal expansion. These advantages would make AgLiGa2Se4 a different promising NLO crystal for mid‐IR laser applications.
