Ultra-Low noise laser diode driver with TEC control & USB

This product is most useful only when the level of noise is a major constraint. It is USB-controlled and contains several libraries for system integration (Labview, DLLs, Python, Hexa etc.). It is also available at board level for OEM integration.


This low noise laser diode driver with integrated TEC controller delivers current which can be modulated internally or externally. It is compatible with any butterfly pinning (Type 1, Type 2, Type 2 Bias-T etc.). Its noise level is comparable with Battery-based drivers and this makes it the most compact low noise laser diode driver with such performances. It is also available at board level to become an ideal tool for OEM integration into your product.

Butterfly Laser diodes such as Thorlabs, II-VI, or low noise external cavity based RIO are perfectly well controlled.

These products are now offered by AeroDIODE, Logo_aerodiodea new ALPhANOV spin-off company. The product manager is available to answer any technical of commercial question.

Product reference: CCS Low Noise
