Are some Laser radar bands undetectable?
I Recently got pulled over by a RI State Trooper who said he clocked me with Laser radar. I had my Escort 9500i on but it never made a peep. Even though it probably would not have helped if "instant on" was also used, I'm troubled by the fact that the detector remained silent. My question is..are there new Laser frequencies that the current crop of detectors may not pick up?...PS..is it time for a Valentine One??

I think the RI State Troopers use the Donut method.....they drop the donut as you go by and count the seconds till it hits their belly, divide by 5 and add 70. Most court systems say Troopers can tell your speed just by watching you as you approach. In fact they have diploma's from Dunkin Donuts....errr Trooper School saying just that....

The laser beam is tight, only 15-18" in diameter at the distances commonly used. Unless it is aimed at your detector, you won't get an alert. If the cop aims at your front bumper, it's undetectible. Your radar detector will never see it. It's a beam of infrared, by the way.

Huh? The only way to "jam" a laser (lidar) is (a)not have anything on your car that reflects light or (b) send back a much more powerful beam of infrared. For (b) to work you have to detect the lidar to begin with, and that is iffy for the reason I outlined above.
Think of a laser pointer. It's not at all like radar. In a speed trap where the trooper is only a few hundred feet from you, the beam may be only 6 inches wide. While the trooper could aim at your windshield, he can make it less detectible by aiming at a foglight or a front plate.

The jammer sends out beams that block the laser from hitting your car.

Mounts in the front clip and close enough to the headlights (and front plate if you run one) to work like a charm.
Just remember to flip the switch/turn it off once you slow down so they actually get a reading.

Read my post again, the beam is superceded, not intercepted. If you are thinking of a passive system, they simply don't work very well as they depend on absorbing the beam. An active jammer, one that can return a powerful laser of your own back to the gun, is the only reliable jammer. But the Achilles heel is detecting the beam in the first place, for which you a detector with several detection "heads" placed on the car.

A Laser Jammer has to be able to detect the incoming laser beam, alert the driver to slow down, and then transmit a light noise signal that confuses the laser gun, such that the laser gun does not display a speed. Since a laser gun transmits a series of pulses, then the laser jammer has to be able to quickly recognize the incoming laser, and respond accordingly. A good laser shifter will analyze the laser beam coming in and know which laser gun is being used. A poor laser scrambler simply emits a constant stream of light noise, which any laser gun can disregard.
Knowing which jammer is good and which is poor, is a good thing to investigate. Good laser jammers, obviously, will instantly detect a laser gun, alert the driver and jam the laser gun at any distance all the way to the laser gun. This is called "JTG", Jam to Gun. However, there are very few good, laser jammers, that can operate to this level of performance. Blinder M25, M45 Laser Jammer, Passport ZR4 are three of the best laser jammers.
I have the Passport ZR4 and it works as advertised. It's linked to my Passport 9500 radar detector. The laser gun simply cannot get a reading. There is a sensor for the front and back.

My Escort alerts me when instant on laser is being used 1/2 mile ahead of me on the interstate.

get a blinder m27.also has park assist to help you save your licence and the front of your car.

jamming radar is a violation of FAA and probably more than a few federal and state laws.
Laser on the other hand -- free game. Here in Texas it's all good, I bought and installed the Quad Laser Interceptor system (about 800 dollars I think at the time) but it simply works. Saved my *** more than a few times when deployed properly.
