High-voltage pulse with adjustable delay
High-voltage pulse with adjustable amplitude
Two additional sync channels
High contrast
Low jitter
Applications
- Pulse selection
- Pulse Slicing
- Q-switching
Pulse pickers
The pulse picker consists of the pockels cell, high voltage driver, synchronization and delay generator. It is suitable for single pulse selection from train of femtosecond or picosecond pulses. Also the device is used for pulse slicing in order to increase contrast.
