Can a laser diode module be modulated?

Unless specifically labeled as "modulated", our laser diode modules are continuous wave (CW) and cannot be modulated due to an internal feedback loop that reads the laser as "on" for a frequency higher than 40 Hz. Since this is rather slow, it doesn't make modulation practical. Modulated units are specifically designed for faster "on-off" applications. For specific available modulation frequency ranges, please review our various series of Modulatable Laser Diode Modules.
