The USG Series Kilowatt High Power Laser Diode Driver delivers incredibly stable output even at maximum output levels for the most demanding applications. Featuring a tight feedback control circuit and minimal current droop, this driver is state of the art.

Highlights

  • Ultra-High Current Laser Diode Driver: Up to 10KA/100us QCW
  • Huge Power & Energy per Pulse: 2MW & 200 Jule per Single Pulse
  • Powerful QCW Capacitor Charging Power Supply for Kilowatt Laser Diode Driver: Tight feedback circuit to keep a stable and precise constant current
  • Huge Capacitor Bank: up to several F (Farad) for the Best Current Droop at High Current & Long Pulse
  • Touch Panel Control: Optional tablet terminal can be a touch screen control
  • High current/High voltage/High Speed Laser Diode Driver: 10KA/180V at 5us rise/fall time
  • Double Isolated USB 2.0 Interface for highest noise immunity in harsh industrial environments

USG-5000/QCW/USB 10KA  High Current Laser Diode Driver

  • Built in the Oscilloscope: No need any expensive instruments to measure & watch LD waveforms!
  • Easy Control: Everything is controlled by user’s PC, or Optional Tablet Terminal
  • Digital Oscilloscope/Spectrum Analyzer/Pulse Generator as Options: up to 10MHz/60MHz and100MHz-500MHz bandwidth as an option
  • High speed current sensing device to sense and display in real time.  Output current is sampling and regulated every micro-seconds.  This technique guarantees the precise constant current control for customer’s wide range of Laser diodes.
  • Output Voltage Selection features to maximize the 100% output power at very low output voltage: USG-XXXX/QCW can maintain 100% of rated output power even at 30% of rated output voltage.  This is also a unique feature of LIC’s LD drivers.
