Lithium triborate (LiB3O5, LBO) crystal LiNbO3

non-linear opticallaser

Transparency range 350 – 5500 nm Dimensional tolerances +0/-0.1 mm Length tolerance ±0.1 mm Orientation accuracy of cut angle <30 arcmin Surface quality 10-5 S-D Surface flatness <λ/8 @ 632.8 nm Parallelism error <20 arcsec Perpendicularity <5 arcmin Protective chamfers 250 MW/cm2 for 10 ns pulses @ 1064 nm LiNbO3 is also one of the most attractive materials for optoelectronics. A great variety of devices has been developed based upon this material having unique electro-optical, photoelastic, piezo-electric and non-linear properties combined with good mechanical and chemical stability and wide transparency range. Altechna offers a lot of products made of high quality LiNbO3 crystals of both Acoustical and Optical grades. Typically, Czochralsky grown and poled along Z-axis boules are used with sizes up to 80 nm in dia. and 100 mm in length. Other boules orientations can be applied for some purposes (SAW surstrates, piezotransducers).
