Product Description
CASTON's BBO Electro-Optic Modulators
BBO EOM Features:
1.UV Transmission
2.Low Insertion Loss
3.Small Piezoelectric Ringing
4.Resonance Free Operation
5.High Average Power Handling
5.High Contrast Ratio (up to 2000:1)
6.High Speed Switching (up to 30 KHz)
7.High Damage Threshold (> 20 KW/cm2, CW)
As the common and commercial choice of electro-optic crystal used for high average power TFM applications, BBO has significant advantages over other crystals such as LiNbO3 and KTP. The wide transparency range (from 200nm to 3000nm) of BBO allows it to be used in diverse applications.
It has electro-optic coefficients γ11= 2.7pm/V and γ22, γ31<0.1γ11. It is ideal for Q-Switching of CW DPSS lasers with average power>50W at sub-nanosecond speeds.
Vπ of BBO EOM with single crystal of different apertures are 6.8KV (2.5x2.5 mm), 8.0KV (3x3 mm), and 10.8KV (4x4 mm) at 1064nm. BBO EOM with two crystals in series is suitable for TFM with larger aperture and/or lower Vπ.
CASTON provides Z-cut BBO crystals with high performance, AR-coatings and Cr/Au-electrodes for high power applications.
