These are the Berkeley Nucleonics pulse generators, laser diode drivers, and high-voltage and high-current supplies, engineered for capacitive and low-impedance loads in mass spectrometry, laser systems, LiDAR, accelerators, and directed-energy research.
From capacitive-load high-voltage pulse generators to high current laser diode drivers to precision DC supplies that reach 30 kV, the DEI Division covers the full chain of pulsed and high-voltage power. Pick the group that matches your load, then drill into the model that fits.

Capacitive-load-optimized pulsers with nanosecond-class edges and built-in voltage and current monitors. Drive deflection and extraction plates, Pockels cells, Q-switches, microchannel plates, and image intensifiers from an externally supplied high-voltage rail.

Current-mode drivers for diode lasers, bars, and arrays, running QCW, CW, and pulsed modes with fast current edges. Output protection and compliance control keep the load safe while you push it into low-impedance pulse work.

Precision high voltage DC power for the bias and rail side of pulsed-power systems. The PVP Series delivers regulated output to 30 kV for detector and PMT biasing, electrostatic work, and general high-voltage test, with the stability metrology and accelerator work demand.
Directed Energy, Inc., founded in 1987, built a respected line of high-voltage pulse generators and laser diode drivers. It is now the DEI Division of Berkeley Nucleonics. The same designs and the same California build carry forward, backed by BNC's instrumentation depth and a single support path for the whole signal-to-power chain.
Output stages tuned for capacitive and low-impedance loads, where charge transfer and edge speed, not power into 50 ohms, set the limit.
Half-bridge totem-pole outputs deliver fast, symmetric rise and fall with low ringing for clean high-voltage transitions.
Built-in voltage and current monitor outputs let you watch the pulse the load actually sees, without inserting external probes.
Over-current detection and shutdown guard the driver and the load against faults during fast, high-current pulse work.
Choose OEM modules for system integration or benchtop instruments for the lab, sharing the same output architecture.
Pair the pulsers with BNC pulse and delay generators and AWGs for a single-vendor timing chain from trigger to load.
Each application ships with a technical brief covering the load, the method, and the model that fits. See the documentation library or submit your application.
