Nonlinear large nonlinear coefficient Beta Barium borate used in electro optical applications

Product Overview

Description

Good mechanical and physical properties of large nonlinear coefficient Beta-Barium borate

 is a nonlinear optical crystal with a combination of unique features:

• Wide transparency region


• Broad phase-matching range


• Large nonlinear coefficient


• High damage threshold


• Wide thermal acceptance bandwidth


• High 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 acceptance bandwidth, high damage threshold and small absorption BBO well suits for frequency conversion of high peak or average power laser radiation. The large spectral transmission range as well as phase matching, especially in UV range, makes BBO perfectly suitable for frequency doubling of Dye, Arion and Copper vapour laser radiation, effective cascade harmonic generation (Frequency doublers, triplers, parametric amplifiers and wave mixers) of wide spread Nd:YAG as well as of Ti:Sapphire and Alexandrite laser radiation. Both angle tuned Type 1 (oo-e) and Type 2 (eo-e) of phase matching can be obtained increasing a number of advantages for different applications.
