QCL Series Low Noise Quantum Cascade Laser Drivers


Product Introduction

QCL Series Low Noise Quantum Cascade Laser Drivers

The Low Noise QCL Drivers employ advanced patented1 circuitry to deliver the lowest current noise density of any commercially available driver. Powering your QCL with this driver will enable better performance—at lower cost, and in less time—than otherwise possible. This is the right driver for lasers that require a high-precision and ultra-low noise current source: the 500 mA QCL laser driver exhibits noise performance of 0.4 μA RMS to 100 kHz, and an average current noise density of 1 nA / √Hz.



- Output current of 500 mA, 1 A, 1.5 A, or 2 A  

- Low noise: < 0.4 μA RMS up to 100 kHz (typical) 

- Compliance voltage up to 20 V 

- 3 dB bandwidth 2 - 3 MHz; 250 nsec rise time 

- Constant Current Mode operation 

- Safety features protect your QCL investment
