Preliminary experiments have indicated this stoichiometry-dependent mid-IR absorption in AgGaSe(2) crystals may be significantly minimized by optimization of the process parameters through crystal progress and annealing.

for example LixAg1−xGaS2 and LixAg1−xGaSe2, the structural distortions in LixAg1−xInSe2 are far more well known.

Invented Pretty much in exactly the same time as BBO, LBO has the highest injury threshold, and greater internal crystal high quality than BBO. LBO can reach non-vital section matching for SHG1064nm about 150C, which in addition to its high problems theshold, can make LBO the very best SHG crystal for prime ability 1064nm devices. DKDP (deuterated KDP), KDP, ADP were the first commercially obtainable NLO crystals . The merits of DKDP or KDP include things like Value-performance and large sizing availability. For large apertures, for instance Individuals about 50mm, DKDP, KDP and ADP are the only selections. KNbO3's conversion efficiency is superb. And immediate SHG of diode lasers has presently been reported. Even so the click here multi-area-issue is its main disadvantage. LiIO3 has a substantial conversion performance, and it is simple to acquire in major dimensions. However the hygroscopicity and small harm threshold limit its programs. AgGaS2 and AgGaSe2 are A very powerful NLO crystals in IR ranges, since a lot of the previously mentioned NLO crystals are only clear in noticeable or around-IR array. The everyday use of both of these crystals are as SHG of CO2 lasers, and OPO crystals to deliver IR or far IR radiations. How can you pick the right NLO crystals? Here's the listing of issues you have to answer:

The alternative of fifty percent of the significant Ag�?cations with gentle Li�?raises the band gap to two.2 eV (vs. one.7 eV in AgGaSe2). The LDT price in AgLiGa2Se4 raises 5 moments in comparison with that in AgGaSe2, while preserving a relatively substantial NLO susceptibility of 26 pm V⁻�? In addition, the thermal enlargement coefficients in AgLiGa2Se4 are around two times decrease in complete worth as opposed with AgGaSe2, which is beneficial to the massive crystal development. All of these benefits would make AgLiGa2Se4 a different promising NLO crystal for mid‐IR laser applications.
