60 A Pulsed/CW/QCW Laser Diode Driver Module

Categories: , , ,

The PCO-6141 is a compact, OEM-style high power pulsed/CW current source designed to drive diode lasers, bars and arrays in pulsed, QCW or CW modes. It delivers up to 60 A of output current with pulse widths from less than 100 ns to DC and pulse repetition frequencies from single-shot to 500 kHz at duty cycles up to 100%.

The PCO-6141 features a user-adjustable variable rise time control. This innovative feature allows the user to adjust the rise time within a range of 1.5 μs by means of a PCB-mounted potentiometer to optimize the driver’s rise time for the user’s application.

The PCO-6141 is based on a hysteretic, average current, switch-mode regulator. This type of regulator is a variable-frequency, variable pulse width design which maintains current in an energy storage inductor between a minimum and maximum level. This architecture provides a high-performance driver in a small form factor, with high operating efficiency and low stored energy.

At 60 A output current, the stored energy in the driver is approximately 7 Joules, dramatically lower than the stored energy in comparable linear current sources.

  • 0 A To 60 A Output
  • Less than 100 ns to DC Variable Pulse Width
  • 20 V Maximum Output Voltage
  • 1.2 kW Maximum Average Output Power
  • User-Adjustable Variable Rise Time
  • Repetition Frequency Single-Shot to 500 kHz

The PCO-6141 is designed to drive diode lasers, bars and arrays in pulsed, QCW or CW modes. The rugged, compact design and high power capability of the PCO-6141 make it an excellent OEM choice for driving high-power laser diodes.
