LBO Crystal
THATSHIGH's LBO (Lithium triborate or LiB3O5) is grown with an improved flux method. LBO is an orthorhombic cyrstal and belongs to the point group mm2. It is built up of a continuous network of B3O7 groups with lithium cations locating in the interstices. The compact network of B3O7 groups makes the LBO crystal almost free of inclusion. Now, THATSHIGH provides high quality LBO crystals for many applications. THATSHIGH offers: 1. Strict quality control. 2. Large crystal with size up to 10x10x30 mm3 and maximum length of 35 mm. 3. AR-coatings, mounts and repolishing services. 4. Fast delivery, in-stock crystals in a large quantity. No visible scattering paths or centers when inspected by a 30 mW green laser Quality warranty period: one year under proper use NOTE: 1. LBO has a very low susceptibility to moisture. Users are advised to provide dry conditions for both use and preservation of LBO. 2. Users are advised to cautiously protect polished surfaces of LBO. 3. THATSHIGH engineers can select and design the best crystal for you if parameters of your laser are provided, for example, energy per pulse, pulse width and repetition rate for a pulsed laser, power for a cw laser, laser beam diameter, mode condition, divergence, wavelength tuning range, etc.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
