There's no such thing as a "Federal Laser License". There are State regulations that vary by type and usage, but these are health and safety rules. (Grounding, interlocks, workplace environment, etc.) Others (excimer lasers) have air quality regulations on how you handle and vent their gasses. Federal regulations are generally limited to labeling requirements on products.

Lasers are licensed by the Nuclear Regulatory Commission. I found this out the hard way when some of my techs in an OEM Dept. were playing with a Cadium/Helium Laser used for Laser Based Recorders.
