Lidatek has(had?) a working laser jammer on the market.There was an independent organization that tested them and found them to work. I believe there are not any Federal laws on laser jamming,but many States have laws on their books about them,usually something about interfering with law enforcement.
The main problems with laser jamming are the narrow beamwidth and getting enough optical power to the laser gun to overcome their signal.The laser gun can have a narrow field-of-view to receive the reflected signal,but the jammer has to send a wide beam to insure some of the signal gets to the narrow view of the laser gun at whatever angle the speed gun is off the axis of your vehicle.The wide beam necessary reduces your effective output power to the speed gun. Jamming would also be more apparent to the speed gun operator.
Then there are pbuttive measures that can be used with laser speed guns;reducing the reflected pulses from your vehicle by darkening surfaces that would reflect them.Getting rid of any front plate would be the 1st step,then somehow shielding your headlights and front turnsignals would be #2. Then blackening any chrome or shiny surfaces. -- Jim Yanik jyanik at kua.net
