Laser Diode Keyes for Arduino

"

retrolefty:
This is an example of a simple 'raw' laser diode component. It was designed to be driven from a automatic constant current driver circuit that utilizes the 'sensor' pin from the diode as a feedback signal to tell the current driver to raise or lower the current to maintain a constant output with changing ambient temperature, device temperature, etc.

Does the code or driver exist, so that we can integrate it into an arduino board ?
