CHIRON 3
BBO Pockels Cell
PRODUCT DATASHEETChiron 3 BBO Pockels cell raises the bar
for high repetition rate and highaverage power laser applications.
The Chiron 3 BBO Pockels cell design builds on thedual crystal geometry successfully used to minimize
drive voltage (~2.3 kV quarter-wave voltage @1064 nm for the Chiron 3). BBO Pockels cells
operate from approximately 0.2 to 1.65 µm and are
not subject to tracking degradation. Due to thelow piezoelectric coupling coefficients of BBO, theChiron 3 functions at repetition rates up to 1 MHz.
Chiron Pockels cells work in regenerative amplifiers,
high pulse repetition rate micro-machining lasers,
and high-average power lasers for material
processing and metal annealing.

Key Features• High pulse rate operation to 1 MHz• Solid state – no index matching fluid• Low acoustic noise• Damage resistant ceramic apertures• Compact design• High-reliability• Operation at high average power
Key Benefits• Ideal for high average power systems• Low absorption leading to reduced thermal
lensing/thermal depolarization• Exceptional high repetition rate performance• Excellent, accessible technical support
Applications• Military• OEM and replacement laser systems:‒ Machining, marking, via drilling‒ Ophthalmology‒ Q-switching and regenerative amplifiers‒ Research
