Preliminary experiments have indicated that this stoichiometry-dependent mid-IR absorption in AgGaSe(2) crystals may be significantly lessened by optimization of the procedure parameters throughout crystal growth and annealing.

including LixAg1−xGaS2 and LixAg1−xGaSe2, the structural distortions in LixAg1−xInSe2 are far more popular.

(LIDT) and optical birefringence is The crucial element to get the excellent NLO crystals for harmonic mid-IR coherent

So, a good selection is a BBO with a hundred micron thickness as this next harmonic generator. To learn more, you should Be at liberty to Speak to the United Crystals' seasoned specialized help group. Simply click here to get a quote by means of e-mail

AgGaSe2 and LiGaSe2 are two renowned mid‐infrared nonlinear optical (NLO) products with comparable chemical system but distinct structural symmetry. The previous material has relatively bigger NLO result and birefringence but alternatively small Power band gap, even though the latter is the opposite. Aiming at acquiring a great stability of NLO Homes, here the substitution in between silver and lithium ions on ... [Exhibit total abstract] the evolution of structural and optical properties in a brand new series of LixAg1–xGaSe2 crystals is systematically investigated. It reveals that, with the increase of Li content material, LixAg1–xGaSe2 almost keeps exactly the same tetragonal symmetry with AgGaSe2 till x �?0.

Usually, not all responses to the above inquiries are "Yes", so You must stike a equilibrium among these variables to locate the best Resolution in your systems. As an example, to acquire a more info SHG crystal for Ti:Sapphire laser at 800nm, with the heart beat width of 40fs, and the anticipated pulse broadening result a lot less than 20fs. KTP, AgGaSe2 or AgGaS2 cannot achieve phase matching of SHG800nm; LiIO3's injury threshold is just not significant more than enough; Each BBO and KDP are appropriate, nonetheless, BBO's conversion effieicy is increased than KDP, and 100micron BBO SHG800nm can only make pulse broadening influence of 19fs.

Premium quality AgGaSe2 solitary crystals with twenty mm in diameter and fifty five mm in size are developed by Bridgman system. It is actually identified that there is a 2nd stage of Ag-prosperous Ga2Se3 (or named AgGa7Se11) while in the AgGaSe2 crystal.

Get entry to the full Model of the written content by using among the obtain choices down below. (Log in alternatives will look for institutional or personalized obtain. Material may possibly demand buy if you do not have entry.)

The replacement of 50 % with the weighty Ag�?cations with light Li�?improves the band gap to two.2 eV (vs. 1.seven eV in AgGaSe2). The LDT benefit in AgLiGa2Se4 boosts 5 moments when compared with that in AgGaSe2, whilst preserving a relatively significant NLO susceptibility of 26 pm V⁻�? Additionally, the thermal expansion coefficients in AgLiGa2Se4 are about two times reduced in complete value in comparison with AgGaSe2, which is helpful to the massive crystal development. These benefits would make AgLiGa2Se4 a whole new promising NLO crystal for mid‐IR laser apps.
