Seek for new inorganic 2nd harmonic era materials that can be used in mid-IR area is just one of the current frontier topics in the sector from the nonlinear optical supplies. This paper opinions the development to the materials previously two decades, such as the seek out new supplies and enhancement of crystal high quality of the acknowledged components.
So, a good selection is actually a BBO with a hundred micron thickness as this next harmonic generator. For more info, make sure you feel free to Get hold of the United Crystals' knowledgeable technical support group. Click the link to get a quote by way of e-mail
The use of a LiTaO(3) retarder is suggested to realize an orthogonal state of polarization concerning OPO outputs which might be necessary for effective pumping of the AgGaSe(2) crystal.
AgGaSe2 and LiGaSe2 are two famous mid‐infrared nonlinear optical (NLO) elements with related chemical formulation but unique structural symmetry. The former substance has comparatively more substantial NLO impact and birefringence but fairly small Electricity band hole, although the latter is the opposite. Aiming at attaining a great balance of NLO Attributes, below the substitution in between silver and lithium ions on ... [Present total abstract] the evolution of structural and optical Qualities in a new series of LixAg1–xGaSe2 crystals is systematically investigated. It reveals that, with the rise of Li content material, LixAg1–xGaSe2 Nearly keeps precisely the same tetragonal symmetry with AgGaSe2 until finally x �?0.

AgGaSe/sub 2/ crystal progress has actually been recognized by an improved Bridgman strategy with just a one-zone vertical growth furnace. The method is to help make the strong-liquid interface transfer from the bottom…

High-quality AgGaSe2 one crystals with twenty mm in diameter and fifty five mm in duration are actually developed by Bridgman technique. It's located that there's a 2nd period of Ag-prosperous Ga2Se3 (or named AgGa7Se11) during the AgGaSe2 crystal.

The alternative of 50 % of the significant Ag�?cations with light-weight Li�?enhances the band gap to two.2 eV (vs. 1.seven eV in AgGaSe2). The LDT price in AgLiGa2Se4 will increase 5 situations in comparison with that in AgGaSe2, though preserving a comparatively huge NLO susceptibility of 26 pm V⁻�? Also, the thermal growth coefficients in AgLiGa2Se4 are about two occasions decrease in complete benefit compared with AgGaSe2, which is beneficial to the big crystal development. All of these rewards would make AgLiGa2Se4 a completely new promising NLO crystal for mid‐IR laser programs.
