DEI
Directed Energy Division

From Directed Energy to Berkeley Nucleonics

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.

Why these pulsers

Edges, monitors, and protection.

Capacitive Load

Optimized output

Output stages tuned for capacitive and low-impedance loads, where charge transfer and edge speed, not power into 50 ohms, set the limit.

Totem-Pole

Half-bridge stage

Half-bridge totem-pole outputs deliver fast, symmetric rise and fall with low ringing for clean high-voltage transitions.

V & I Monitors

Built-in readback

Built-in voltage and current monitor outputs let you watch the pulse the load actually sees, without inserting external probes.

Protected

Over-current shutdown

Over-current detection and shutdown guard the driver and the load against faults during fast, high-current pulse work.

OEM & Bench

Two form factors

Choose OEM modules for system integration or benchtop instruments for the lab, sharing the same output architecture.

One Vendor

Single timing chain

Pair the pulsers with BNC pulse and delay generators and AWGs for a single-vendor timing chain from trigger to load.

Applications

Where these pulsers go to work.

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.

Flagship

Time-of-Flight Mass Spectrometry

Fast, clean deflection and extraction-grid pulsing for time-of-flight instruments, the application the PVX-4141 and PVX-4110 were built around.

 Lasers

Pockels Cell & Q-Switch Driving

High-voltage, low-jitter pulses to switch laser cavities, with the symmetric edges Pockels cells and Q-switches demand.

 Photonics

Laser Diode & Array Driving

Current-mode drive for diode lasers, bars, and arrays in QCW and CW modes, with compliance control and output protection.

 Sensing

LiDAR & Rangefinding

Fast, repeatable high-current pulses for time-of-flight LiDAR and laser rangefinding front ends, from PCO-class modules.

 Directed Energy

Directed-Energy & HEL Systems

High-current array drive and pulsed-power building blocks for high-energy-laser and directed-energy research, drawing on the DEI heritage.

 Accelerators

Accelerators & Beam Kickers

High-voltage pulse generators for beam kickers and deflectors, paired with precision high-voltage supplies for the static bias rail.

 Electro-Optics

Electro-Optic Modulation & Gating

Pulsed high voltage for electro-optic modulators and for gating microchannel plates, PMTs, and image intensifiers.

 HV Test

HV Test & Detector Biasing

Precision high-voltage DC for detector and PMT biasing and for general high-voltage test, from the PVP Series supplies.
