Description

PLD5000 5 A Laser Diode Driver

The PLD Series Laser Diode Drivers deliver the reliability and performance you expect from a Wavelength Electronics laser driver in a compact and easy-to-integrate package. Tens of thousands of PLD drivers are deployed in laser systems around the world, proving beyond doubt the reliability and stability of the design. PLD Series drivers are found in particle counters, manufacturing vision systems, photovoltaic quantum efficiency testers, wavefront scanners, fiber aligners, and laser diode LIV testers.

The PLD drivers operate from a single 5 V power supply. To accommodate high compliance lasers, or multiple stacked lasers, the PLD laser diode drivers allow the laser to be driven from a separate power supply up to 30 V.

The available PLDEVALPCB evaluation circuit board reduces your development costs and allows you to focus on designing the features that will set your system apart.

Thoughtfully designed features provide valuable benefits and protect the laser against operational anomalies:

  • Remote enable can be tied to a safety interlock and a temperature controller, such as Wavelength's PTC Series.
  • Built-in constant current and constant power operating modes minimize your electronics overhead.
  • On-board controls mean quick and easy driver setup.
  • Analog setpoint input gives you remote external control of the laser current and modulation.
  • Latching current limit safely switches off output if current limit is reached.
  • Short-term Current Stability at ambient 25 °C: less than 100 ppm
  • Supply Range: 5 - 30 V
  • PCB mount package size: 45 x 67 x 39 mm
  • Delay: 1.5 sec. After the delay, current will rise to the level dictated by the setpoint voltage. This delay ensures that all control electronics are functioning before current flows to the laser diode. The delay time is set with internal components
  • Current Ramp: 250 msec (to full scale)
  • Rise / Fall times: 3 µsec (to full scale) / 12 µsec
  • Remote Enable: The laser current is enabled if this input is +3 to +5 V. The current is disabled if the input is grounded or floating. This input is called LD ENABLE.
  • Bandwidth: 150 kHz (CC). Bandwidth in Constant Power mode will depend on photodiode response.
  • Maximum Power Dissipation: 15 W
