The logical solution here is not to speed. Pretty simple really.
Nothing will protect you from lasers. The calculation of speed is done quicker than the detector is able to warn you that there's a laser pointing at your car, if the detector is able to detect that at all, which most can't.
I don't know if you Americans have fixed speed and red light cameras, but the detection field of a fixed speed camera is extremely short. By the time you're even aware of a signal hitting your car the system has calculated your speed.
