Preliminary experiments have indicated this stoichiometry-dependent mid-IR absorption in AgGaSe(two) crystals could be significantly decreased by optimization of the procedure parameters throughout crystal development and annealing.

Injection-seeded optical parametric oscillator for economical variation frequency generation in mid-IR
Optical rectification in the chalcopyrite AgGaSe2 crystal for broadband terahertz radiation era
So, a good choice is a BBO with one hundred micron thickness as this 2nd harmonic generator. For more information, remember to feel free to Call the United Crystals' seasoned technological help workforce. Click the link to secure a estimate by means of e-mail
It's concluded by conversations with the DTA results as well as period diagram that solitary crystals grown from polycrystalline components with stoichiometric composition must have a next period of Ag-prosperous Ga2Se3. This consequence is useful for the heat remedy, through which what and…
This may reveal the minimal crystallization location within the stage graph read more in the tetragonal composition LixAg1−xInSe2.

Crystal framework with the AgLiGa2Se4 device mobile. The ellipsoids are drawn with the eighty% probability level.
A tunable mid-infrared optical parametric oscillator continues to be demonstrated using a noncritically stage matched AgGaSe/sub 2/ crystal with pump wavelength tuning. Regular electricity experiments have…
Top quality AgGaSe2 one crystals with twenty mm in diameter and fifty five mm in length are grown by Bridgman system. It really is observed that there is a 2nd section of Ag-wealthy Ga2Se3 (or named AgGa7Se11) within the AgGaSe2 crystal.

The substitute of 50 % from the weighty Ag�?cations with mild Li�?boosts the band gap to 2.two eV (vs. 1.7 eV in AgGaSe2). The LDT worth in AgLiGa2Se4 improves five situations when compared with that in AgGaSe2, even though preserving a relatively massive NLO susceptibility of 26 pm V⁻�? Additionally, the thermal expansion coefficients in AgLiGa2Se4 are around two times reduced in complete value as opposed with AgGaSe2, which is beneficial to the large crystal growth. All of these rewards would make AgLiGa2Se4 a brand new promising NLO crystal for mid‐IR laser apps.
