Injection-seeded optical parametric oscillator for successful variation frequency era in mid-IR
Progress advancement of AgGaSe2 one crystal utilizing the vertical Bridgman method with steady ampoule rotation and its characterization

The use of a LiTaO(3) retarder is advised to achieve an orthogonal point out of polarization amongst OPO outputs which are essential for productive pumping of the AgGaSe(2) crystal.

Determined by the big dimensions Li0.81Ag0.19InSe2 solitary crystals of optical good quality, the spectroscopic Homes are
Massive crystals of silver selenogallate have been grown. Generation of the 2nd harmonic of CO2 laser radiation in these crystals was examined. An Electricity conversion effectiveness of 19.8% was achieved.…
Typically, not all solutions to the above inquiries are "Indeed", so You will need to stike a balance amongst these variables to discover the most effective Answer in your techniques. One example is, to get a SHG crystal for Ti:Sapphire laser at 800nm, with the pulse width of 40fs, as well as predicted pulse broadening influence under 20fs. KTP, AgGaSe2 or AgGaS2 can't realize stage matching of SHG800nm; LiIO3's hurt threshold is just not higher adequate; Both equally BBO and KDP are appropriate, on the other hand, BBO's conversion effieicy is bigger than KDP, and 100micron BBO SHG800nm can only create pulse broadening outcome of 19fs.
Digital transitions plus the band gaps Eg step by step maximize as the lithium content improves, according to

The substitute of 50 % on the large Ag�?cations with light Li�?enhances the band gap to two.2 eV (vs. one.7 eV in AgGaSe2). The LDT benefit in AgLiGa2Se4 will increase 5 moments in comparison with that in AgGaSe2, while preserving a relatively substantial NLO susceptibility of 26 pm V⁻�? Furthermore, the thermal enlargement coefficients in AgLiGa2Se4 are around two situations reduced in complete value when compared click here with AgGaSe2, which is beneficial to the big crystal growth. All of these advantages would make AgLiGa2Se4 a whole new promising NLO crystal for mid‐IR laser applications.
