I found this nifty FAQ regarding jamming LIDAR (Light Identification, Detection, and Ranging).
Here is a quote from the post:
"Is it legal? Jamming lidar is not illegal under FCC rules since they don't regulate this part of the spectrum, but most jurisdictions have a law which makes it illegal to "interfere with the duties of a police officer." I am not a lawyer and the above should not be considered legal advice."
