A laser jammer, like radar jammers, can be broken down into two main types: passive and active jammers.  A passive jammer (whether it relates to laser or radar) does not transmit any electronic signal.  Instead, passive jamming effects the signal by either absorbing or reflecting the incoming radar or laser beam.  The B2 bomber and the F-117 stealth fighter, for example, use a combination of stealth paint, and intricate shape and design to absorb the RF energy of a radar beam and/or reflect the radar beam respectively.

Active jamming on the other hand, known as electronic warfare in the military, involves transmitting an electronic signal (around the 905nm laser gun wavelength) deliberately designed to confuse the radar or laser source.  In the case of laser jammers, this means transmitting an infra-red signal around the same wavelength, and the same frequency as the laser gun.

Laser Diode Jammers vs LED Jammers - what is the difference?

There are two types of active laser jammers; a LED based jammer and a laser diode based jammer.  A LED based jammer uses an array of cheaper LEDs each operating at around 0.4mw in power - just like the one in your TV remote control.  By comparison, laser diodes are capable of operating at a much higher power - up to 75mw and beyond.

So essentially the difference between the two is that a LED based jammer is cheaper to produce, whilst a diode based jammer is much more powerful, although power without good (jamming) software is useless.  Both LED and Diode jammers can be very effective, so long as you understand the limitations.

The downside to a lower powered device is it's limitations at very long range and very short ranges.  At very long distances, the power from the LED's is not strong enough to reach the laser gun, therefore presenting a problem if you were targeted at a very long distance.  Fortunately most laser speed traps are done at a short range (under 1000 feet in the USA) which means longer ranges is usually not a problem.  Short ranges though, can be a problem and this is what is known as "punch through".  When the laser pulse reflections from the laser gun are stronger than the laser pulses transmitted from the LEDs, the the laser gun can actually get a speed reading on your car.  The distance at which this occurs (punch through) varies between models of cars, and models of laser guns.  Again, check out the GOL results for accurate unbiased results.

Cars with lots of reflective frontal surfaces, such as big headlights, fog lights and chrome have more surfaces to reflect the laser gun's pulses back and therefore make it difficult for a laser jammer to do its job. This is why we recommend using Veil anti-laser paint because it effectively masks these reflective surfaces of your vehicle and improves your laser jammer's performance.

A diode based jammer overcomes the power shortfall by operating at a much higher output than the LED based devices, but the downside is a diode is much more expensive to produce.

Not sure which laser jammer is right for you?

There are some products available that promote passive radar and laser jamming, the most well know are the Rocky Mountain Radar products - whom refer to their products as scramblers.  The short answer is passive jammers (scramblers) don't work!  Read our story on how these products are effective at jamming radar as having a tissue box sit on your dash.  Another common "camouflaged" name for laser jammers is a laser diffuser.  Bel for example, market their Bel905 laser difuser as part of their RX75 Pro package.

Laser based speed protection, on the other hand has greater success in both passive and active forms.  Passive protection includes Veil stealth paint, while active includes the Blinder laser jammers, AL, LPP & Laser Interceptor.

Note: The use of Laser Jammers may be illegal in your state or area, therefore you should check your local laws prior to purchase.
