To start with if you don't agree with this post please don't bother responding.
I have owned both the Escort and the M25 laser jammers. Of these 2 the M25 is superior.
They are a real PITA to install and are not invisible on inspection. I know some states have enacted laws prohibiting their use (fortunately not GA yet).
My question is (and I need a real techno type here) would a constant beam of IR light in the appropriate NM range "blind" the laser gun, or is a pulsed return necessary.
I would think that the return the gun gets must be very weak. Obviously the receptor in the gun is very sensitive, but could this also be it's weakness?
No it did not just get a speeding ticket. Haven't had one in 30 years. Lately though there has been a BIG increase in the use of laser here as the local Gov't is looking for revenue anywhere they can find it.
I know we have some sharp techies here on RN. Maybe somebody can answer this question.

Maybe???
6. Overexposure Error - When a laser gun receives an extremely powerful reflective signal, such as a sun flare off a vehicle, the computer's timer can't see return of the 904 nanometer signal it sent. It can't compute a speed reading. In general, the laser gun is looking for the strongest return reflection of its own emitted beam for speed computation.

Can't answer your question, but have one of my own.
I have a 9500ci with laser "diffuser", 2 front 1 rear. I have several "saves" with LEO spotted.
I can't explain a handful of what I believe are laser "falses". All on remote country roads, with no LEO spotted.

The cops have to use a LASER led, but it would seem what would be needed to blind the gun would be a wider beam of IR light as it would not be possible to aim it. What would be needed is power.
I have a hi intensity visible light flashlight and with only 5 LED's it is VERY bright.
The problems with the jammers as I see it are:
1. They can tell when they are being jammed.
2. The jammer makers are fighting a constant battle against improving technology, and they will ALWAYS be one step behind.
I don't want to send back a jamming code, I want to "blind" the unit.
Again I have no technical background of this nature, I just am looking for a way around what I see as another form of taxation.

Gotta admit, I like your train of thought.
A 'permanent' IR array - invisible to the human/naked eye - but visible and 'blinding' to the device which 'channels' our dollars to the state coffers.
As was said, tho', because it would be on 'all the time' - you DO run the risk of being a sitting duck.
Here's a thought...
1) You buy and install a decent laser detector in your car. You have it ON all the time.
2) You install your 'permanent' IR array - and have it on but...
3) You have it so 'wired' to your laser detector - so that, when your laser detector actually detects that you have been 'shot at' - your IR 'jammer' then switches off -- putting you back into 'stealth' mode.
'When one turns on (laser light detected) -- the other turns off (your IR jammer)'.
Since your IR jammer was ON to begin with - it should have had enuf time to blind the laser that was shot at you -- yet now that the laser is off -- so is the IR jammer (so you can't be nailed) -- leaving you to (manually? auto-time-delay circuit?) to turn it back on ...for the next dollar-grabbing event.
As I think more about this - some sort of 'timer' circuit might be on the cards --
1) to leave the IR array ON for a split second after you've been shot (in case the 'ossifer' decides to 'shoot' you more than once (in rapid succession)) - and also to ensure that the IR array has actually stayed on long enuf to actually blind the pulse -- i.e. it *shouldn't* just immediately turn off when you've been 'hit' - but should wait - and THEN turn off
and
2) to automatically 'reset' the IR jammer back to ON so that everything is 'armed' again - for the next episode.

The 9500ci contains 13 LEDs in each of the two forward and one rear diffusers.
It automatically turns itself off for 20 seconds after detecting and jamming a laser signal. This gives you time to slow down and manually turn off the unit.

Although I also run a escort in my car because I love to trounce my car and hate getting tickets, I cannot agree with your comment below.
The motor vehicle codes regarding speeding are there for safety of the greater public, they are not there make you pay another form of taxation.
Why don't you just drive the speed limit and you will never have to pay them anything.

We don't have speed cameras here, we have red light cameras and officers with radar/lasers only so I am not familair with what you are dealing with but I do know that when someone gets nailed running a red light and are not licensed or registered they do get away with it and responsible drivers like me wouldn't.
My point is, if I don't run red lights I won't ever get a ticket, just like the ones who get away with it.
