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

On this research, AgGaSe2 one crystal was successful developed by vertical gradient freezing system. Meanwhile, the precipitates on AgGaSe2 one crystal ended up investigated by x-ray photoelectron…
Optical rectification inside of a chalcopyrite AgGaSe2 crystal for broadband terahertz radiation technology
Matters can be refined further more within the search results. The subject aspect will expose the substantial-stage subjects related to the article content returned inside the search results. Particular COLLECTIONS
It is concluded by conversations With all the DTA results plus the phase diagram that one crystals grown from polycrystalline products with stoichiometric composition should contain a second period of Ag-wealthy Ga2Se3. This final result is helpful for the warmth treatment method, by which what and…

Determined by the massive measurement Li0.81Ag0.19InSe2 one crystals of optical top quality, the spectroscopic properties are
Big crystals of silver selenogallate have been grown. Technology of the 2nd harmonic of CO2 laser radiation in these get more info crystals was researched. An Electricity conversion effectiveness of 19.8% was attained.…
Normally, not all responses to the above inquiries are "Certainly", so You must stike a equilibrium amongst these variables to locate the very best Resolution for your techniques. One example is, to get a SHG crystal for Ti:Sapphire laser at 800nm, with the pulse width of 40fs, along with the envisioned pulse broadening effect under 20fs. KTP, AgGaSe2 or AgGaS2 can't reach section matching of SHG800nm; LiIO3's damage threshold just isn't superior enough; Each BBO and KDP are ideal, on the other hand, BBO's conversion effieicy is bigger than KDP, and 100micron BBO SHG800nm can only produce pulse broadening result of 19fs.
Digital transitions plus the band gaps Eg step by step maximize given that the lithium content increases, in line with
A fresh nonlinear optical crystal Li0.81Ag0.19InSe2 with well balanced Qualities for economical nonlinear conversion while in the mid-IR region
The substitute of fifty percent on the weighty Ag�?cations with light Li�?increases the band hole to 2.2 eV (vs. one.seven eV in AgGaSe2). The LDT benefit in AgLiGa2Se4 boosts five times in comparison to that in AgGaSe2, although keeping a relatively massive NLO susceptibility of 26 pm V⁻�? Also, the thermal growth coefficients in AgLiGa2Se4 are somewhere around two situations lessen in absolute worth in contrast with AgGaSe2, which is helpful to the big crystal expansion. Each one of these positive aspects would make AgLiGa2Se4 a new promising NLO crystal for mid‐IR laser programs.
