AgGaSe2 Crystal - An Overview

Blog Article

Defect-linked absorption and luminescence had been discovered and a way to lower them was prompt. The electronic structure, density of states, and many optical Qualities were being calculated from the main ideas for Li2In2GeSe6. Calculated nonlinear coefficients and rather large birefringence suggest a robust stage-matching means. These investigations demonstrate that Li2In2GeSe6 is really a promising mid-infrared nonlinear optical crystal.

The alternative of 50 percent in the heavy Ag�?cations with mild Li�?increases the band hole to 2.2 eV (vs. one.seven eV in AgGaSe2). The LDT benefit in AgLiGa2Se4 raises 5 occasions compared to that in AgGaSe2, even though retaining a relatively significant NLO susceptibility of 26 pm V⁻�? Additionally, the thermal enlargement coefficients more info in AgLiGa2Se4 are roughly two moments decreased in complete worth when compared with AgGaSe2, which is beneficial to the big crystal development. All of these strengths would make AgLiGa2Se4 a completely new promising NLO crystal for mid‐IR laser apps.
