cut and paste from a laser gun mfg site:

Laser Speed Guns emit a very narrow, intense beam of "invisible" light. The speed of light is a known constant (approximately 300,000 Km per second). Therefore, the laser speed gun calculates distance by measuring the length of time it takes for the beam to travel to a target and back to the gun. Many such readings are taken over a brief period of time to determine how fast a vehicle is traveling. The speed reading "can" be accurate under "ideal" conditions. It is "claimed" that the narrow beam makes target verification more certain than with radar. The Lasers used by enforcement authorities in Australia are made in the USA by Kustom or LTI and operate on a frequency of 904 nanometers. In the states and territories of Australia, Laser Speed Guns have replaced most hand-held radar guns for stationary "point-and-shoot" traps.

now how much to overpower a Laser gun ? Solid or random pulsed ?

Now a Class C misdemeanor in Texas, worth the risk ?
