QBY-4050 Energy-Efficient Pockels Cell Driver Board
QBY-4050 is a compact, efficient Pockels cell driver with very low power consumption, requiring no cooling. It delivers quasi-rectangular bipolar voltage pulses at10kHz with durations of40-1000 ns to control electro-optic-crystal birefringence and change the polarization of transmitted light. QBY-4050 requires a+24V DC supply and a pulse generator to set operating frequency and pulse width. Maximum power is10W for a5pF load at50 kHz and4kV. Output reaches5kV and rates up to50kHz, strongly dependent on load capacitance. Rise and fall times are approximately30-40ns. Analog input adjusts pulse amplitude, while an external LVDS signal controls pulse width. Cooling: cool the driver through its base.
