Description
Beta Barium Borate BBO is a non-linear optical crystal that combines
a number of unique features.
These features of nonlinear BBO crystal include wide transparency               
threshold and excellent optical homogeneity. Therefore, BBO provides
an attractive solution for various non-linear optical applications like
OPO, OPA, OPCPA and other. As a result of large thermal acceptancebandwidth, high damage threshold and small absorption BBO is well
suited for frequency conversion of high peak or average power laser
radiation. The large spectral transmission range as well as phasematching, especially in UV range, makes BBO perfectly suitable forfrequency doubling of Dye, Argon and Copper vapour laser radiation,                        !   "#$%& as of Ti:Sapphire and Alexandrite laser radiation.

Description

Length tolerance

Lithium Triborate LBOs high damage threshold, wide acceptanceangle, good thermal stability and wide transmission range make itideal for frequency doubling of high power lasers.

Orientation accuracy of cutangle

It is unique in many aspects, especially its wide transparency range,
moderately high non-linear coupling, high damage threshold andgood chemical and mechanical properties. Its transmission range
is from 0.16 μm to 2.6 μm. LBO allows temperature-controllable
non-critical phase-matching operation (NCPM) for 1.0-1.3 μm , TypeI SHG, and also provides room temperature NCPM for Type II SHG
at 0.8-1.1 μm. It possesses a relatively large angular acceptancebandwidth, reducing the beam quality requirements for source lasers.
