Preliminary experiments have indicated this stoichiometry-dependent mid-IR absorption in AgGaSe(2) crystals might be substantially decreased by optimization of the process parameters all through crystal advancement and annealing.

The essence of rational structure syntheses of practical inorganic products lies in knowing and Charge of crystal buildings that figure out the physical Houses. AgGaS2 has the very best determine of benefit for IR nonlinear optical interactions so far, but suffers small laser‐induced harm threshold (LIDT). The partial Li substitution of Ag atoms is currently revealed to push up the bottom in the conduction band and flatten the very best with the valence band, resulting in an ultrawide band hole of three.

A brand new nonlinear optical crystal Li0.81Ag0.19InSe2 with balanced Homes for economical nonlinear conversion while in the mid-IR location
The replacement of fifty percent with the significant Ag�?cations with mild Li�?improves the band hole to 2.2 eV (vs. one.seven eV in AgGaSe2). The LDT worth in AgLiGa2Se4 raises 5 times in comparison with that in AgGaSe2, even though trying to keep a relatively big NLO susceptibility of 26 pm V⁻�? Moreover, the thermal expansion coefficients in AgLiGa2Se4 are approximately two periods reduced in absolute value in contrast with AgGaSe2, which is helpful to the massive crystal expansion. Each one of these benefits would make AgLiGa2Se4 a completely new promising NLO crystal for mid‐IR laser applications.
