Sounds like a fun OpenCV type project to use a camera onboard in conjunction with the airplane's gps position,altitude, and camera's orientation to locate the source of the laser and prosecute accordingly.
Prosecution based on such information has been done frequently in the past. Basic geometry convicted a man near me about 6 years ago for shining a green laser pointer at a pilot taking off at a local air force base.
Don't shine lasers at pilots from your backyard.
