Well, not exactly 'allowed to jam it legally'  (interfering with a law 
enforcement officer, or something like that), but if you built a garage door 
opener that works off a 908nm beem of ir led, 20ns pulses at 1KHz, and could 
demonstrate that that was the primary purpose of your device, and it just so 
happen to jam lidar....
(specs from memory, I believe the wavelenght is around 900nm.  Have not seen any 
solid state lasers in that range, though :-(
