Today’s state-of-the-art laser diodes are powerful but sensitive devices requiring high-stability and accurate input power to drive them reliably. AMS Technologies offers a complete range of laser diode drivers / controllers for PCB, chassis or benchtop mount for easy integration into your laser system, featuring high-end technology to provide high performance, low noise and down to well below 1% regulation and current error in order to best power, control and protect your laser diodes.
AMS Technologies’ selection of laser diode drivers addresses the requirements for low, medium and high power laser diodes, whether driving single laser diodes, laser diode arrays or complete diode laser modules. Drivers for quantum cascade lasers (QCL) are also available. Our ultra-compact and highly reliable laser diode controller solutions provide constant current or constant power mode with industry-leading stability, some models also featuring external modulation or computer control.
Standard LD drivers can provide from a few Watts up to kW ranges at a maximum of 250 A. Some of our laser diode drivers include a temperature controller for Peltier (TEC) modules. These laser diode drivers and TEC temperature controllers additionally help to maintain the thermal and spectral stability of the laser diode.
How to Select the Right Laser Diode Driver
To decide which laser diode driver is most appropriate for your application, first sort by your maximum laser diode (LD) current requirement. Then choose what mount option would fit best – components for PCB mount, modules for chassis or benchtop mount or instruments for benchtop or rack mount. For low-noise operation (constant current mode only), our QCL drivers can also be used with laser diodes.
If you can’t find an off-the-shelf laser driver that meets your needs, contact the AMS Technologies laser driver experts – together with our suppliers we can create a laser driver solution tailored to your requirements.
