BBO Pockels Cell Drivers
● HV rise/fall time: 2-4 ns @ 800 V, 6-12 ns @ 2400 V, 10-20 ns @ 4000 V
● HV pulse amplitude up to 4.5 kV
● Pulse repetition rate up to 200 kHz
Pockels Cell Driver for Q-Switching of Flashlamp Pumped Lasers
These drivers are designed for Q-switching of nanosecond flashlamp pumped lasers without use of phase retardation plates, for example to drive a DKDP Pockels cell in YAG lasers for aesthetic therapy. High voltage is applied to Pockels cell in order to inhibit oscillation. Pockels cell is opened by negative polarity pulse allowing laser to radiate.
