Product Overview
Ultra-Low Noise, Benchtop Quantum Cascade Laser Driver
The QCL Series current sources are designed expressly for driving Quantum Cascade Laser Diodes (QCL). In order to maintain their characteristically tight center linewidths and minimize wavelength jitter, quantum cascade lasers must be powered by drivers with exceptionally low current noise density. The 500 mA QCL laser driver delivers noise performance of 0.5 µA RMS to 100 kHz, and an average current noise density of 1.5 nA / √Hz, the lowest available on the market today.
Quantum cascade lasers are used in industrial exhaust sensing, medical diagnostic breath analyzers, safe-distance explosives detectors, and light sources for infrared imaging systems. This benchtop driver is perfectly suited to developing applications that requires fast measurement times and ultra high sensitivity, particularly trace gas sensing in medical and industrial applications.
Comprehensive Control and Safety Features Protect Valuable QCLs
The QCL driver control is easy and intuitive using the front panel touch screen and simple button configuration. All driver functionality is also fully accessible via USB or Ethernet remote control, and analog monitor functions are accessible by a connector on the back panel.
Extensive protection circuitry in designed in to safeguard the QCL against operational anomalies:
- Key switch and external analog interlock for user safety
- Adjustable soft-clamping current limit
- Brown-out, reverse-voltage, & over-voltage protection
- Driver over-temperature protection circuit
- Relay shorts output when current is disabled
Operational Considerations
The QCL driver is designed to deliver extremely low noise drive current to the quantum cascade laser, and certain design factors must be considered for optimum system performance. One of the most important components affecting noise performance is the power supply used to power the QCL driver; select low noise linear power supplies with high stability specifications. Proper grounding technique is also critical: ensure there are no ground loops within the system, and grounding the chassis of the QCL driver will help reduce 50/60 Hz noise.
