Altechna offers a lot of products made of high quality LiNbO3 crystals of both Acoustical and Optical grades. Typically, Czochralsky grown along Z-axis boules are used with sizes up to 80 mm in dia. and 100 mm in length. Other boules orientations can be applied for some purposes (SAW surstrates, piezotransducers).
|Wide transparency range|
|Unique electro-optical, photoeleastic, piezoelectric and nonlinear properties|
|Good mechanical and chemical stability|
|Absorption loss < 0,1 %/cm @ 1064 nm|
Tuning your laser source to other wavelengths? Altechna professionals are here to help you evaluate which nonlinear crystal would be best for the required frequency conversion or it’s optimal configuration in respect of available power, beam size, pulse duration or repetition rate.
Want to build second (SHG) or third (THG) harmonic generators, parametric oscillators vs amplifiers (OPO, OPA), sum (SFG) or difference (DFG) frequency generators designed particularly for your laser? We’re ready for a challenge!
Unsure how to best use Raman, photorefractive, electro-optic or need simply birefringent crystals? Learning how the crystals could be used in various laser applications? We can share our experience with you.
Consult Altechna experts about the best way to reach your result before investing into expensive optics. We provide free technical consulting services that can save you time and resources. Get the most effective solutions for various crystal applications, the needed technical information, and appropriate simulations and optimal optical setup advice from the people who have seen it all.
