Cation and anion co-partial substitution induced centrosymmetric to noncentrosymmetric structural transformation to assemble nonlinear-optical rare-earth oxythiogermanates
Preliminary experiments have indicated this stoichiometry-dependent mid-IR absorption in AgGaSe(2) crystals may very well be substantially decreased by optimization of the procedure parameters in the course of crystal expansion and annealing.

Optical rectification in the chalcopyrite AgGaSe2 crystal for broadband terahertz radiation technology
So, a sensible choice is a BBO with one hundred micron thickness as this 2nd harmonic generator. For more info, please Be happy to Call the United Crystals' knowledgeable technical assist staff. Click this link to obtain a quote via e-mail
Invented Pretty much in a similar time as BBO, LBO has the very best problems threshold, and much better internal crystal top quality than BBO. LBO can accomplish non-crucial phase matching for SHG1064nm about 150C, which coupled with its superior hurt theshold, helps make LBO the very best SHG crystal for prime electrical power 1064nm devices. DKDP (deuterated KDP), KDP, ADP were being the main commercially readily available NLO crystals . The merits of DKDP or KDP involve Expense-effectiveness and enormous dimension availability. For giant apertures, including These in excess of 50mm, DKDP, KDP and ADP are the sole solutions. KNbO3's conversion performance is great. And immediate SHG of diode lasers has now been reported. Even so the multi-area-issue is its main drawback. LiIO3 contains a superior conversion efficiency, and it is easy to obtain in big dimensions. Although the hygroscopicity and lower hurt threshold limit its purposes. AgGaS2 and AgGaSe2 are A very powerful NLO crystals in IR ranges, given that the majority of the earlier mentioned NLO crystals are only clear in seen or around-IR variety. The everyday utilization of these two crystals are as SHG of CO2 lasers, and OPO crystals to deliver IR or much IR radiations. How could you select the correct NLO crystals? Here is the list of issues You will need to answer:
This will explain the minimal crystallization region during the phase graph of the tetragonal construction LixAg1−xInSe2.
According to the big measurement Li0.81Ag0.19InSe2 one crystals of optical excellent, the spectroscopic Attributes are

In most cases, not all answers to the above mentioned thoughts are "Yes", so you have to stike a equilibrium among these elements to discover the finest Resolution for your personal techniques. As an example, to obtain a SHG crystal for Ti:Sapphire laser at 800nm, with the pulse width of 40fs, as more info well as predicted pulse broadening outcome lower than 20fs. KTP, AgGaSe2 or AgGaS2 can't achieve period matching of SHG800nm; LiIO3's injury threshold is not really higher enough; Both BBO and KDP are acceptable, having said that, BBO's conversion effieicy is greater than KDP, and 100micron BBO SHG800nm can only build pulse broadening impact of 19fs.
Premium quality AgGaSe2 solitary crystals with twenty mm in diameter and fifty five mm in size are developed by Bridgman technique. It's identified that there is a second stage of Ag-wealthy Ga2Se3 (or named AgGa7Se11) inside the AgGaSe2 crystal.
radiation generation. In this particular perform, we properly synthesize and grow a whole new NLO chalcogenide crystal
