1.25A Laser Diode Driver PCB Mount - PLD1250

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 particle counters, manufacturing vision systems, wavefront scanners, fiber aligners, and other laser systems around the world, proving beyond doubt the reliability and  stability of the design.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 QCL OEM Series drivers use patented1 circuitry to produce the lowest current noise density of any commercially available QCL driver. The 500 mA QCL driver exhibits noise performance of 0.5 µA RMS to 100 kHz, and average current noise density of 1 nA / √Hz - the lowest available. In order to maintain their characteristically tight center linewidths and minimize jitter, quantum cascade lasers must be powered by drivers with exceptionally low current noise density. Our customers have reported achieving narrower linewidths with these drivers than any other they've used.Key Features Off-the-shelf models at 500 mA, 1 A, 1.5 A, 2 A Can be delivered in other current ranges up to 2 A Compliance voltage 16 V (standard), Compliance 7-20 V with factory modification Safety features protect your QCL investment Adjustable soft-clamping current limit Brown-out, reverse-voltage, & over-voltage protection Driver over-temperature protection circuit Relay shorts output when current is disabled Local and Remote Power-On and Enable control,TTL-compatible Analog modulation input between -5V and +5V.

The PLD10K-CH is a 10 A Laser Diode Driver in a small chassis mount package. Operating from a single +5 V supply minimizes internal heat dissipation. Modular packaging makes it easy to integrate the PLD into your system. For applications that require a higher forward voltage, a separate laser diode power supply input lets you provide a higher compliance voltage.Key Features Models: 5 A, 10 A, 12.5 A 5 A and 10 A models operate from a single 5 VDC supply; 12.5 A model requires two supplies Separate power supply can be used to drive high-compliance lasers up to 28 V Constant Current or Constant Power modes Safety features protect your laserAdjustable latching current limitSlow-start circuitry Local and Remote Enable controls
