Barium borate crystal (BBO)
BBO crystal is a new type of UV frequency doubling crystal. In nonlinear optical crystals, is a kind of comprehensive advantages, good performance of the crystal, it has a very wide transmission range, large phase matching, high conversion efficiency, the laser damage threshold is very high, wide temperature matching and excellent optical uniformity, especially for Nd:YAG three laser SHG is widely used.
» Large nonlinear optical coefficients
» Large phase matching range
» Through band width
» High damage threshold of laser
» Heat absorption bandwidth
» Good optical uniformity
It is widely used in two times, three times, four times and five times frequency of 1064nm Nd:YAG laser. Two times frequency, three frequency doubling, sum frequency and difference frequency of dye laser and titanium sapphire laser, optical parametric oscillation, amplifier, electro-optical Q and so on.
