Lasertag gun with red laser

Axel · Feb 4, 2008

Hi:

I own some lasertag guns with 650 nm 1mw red lasers. The law in my country allows a maximum of Class II laser module (1mw). Last week, I visited a leisure center of one competitor and their lasergun shows a more brighter and more visible red laser beam than mine.

How I can have a more brighter and more visible laser beam? My clients are children ,and for them it is more important to see the laser beam rather than the laser dot.

May be using a 635nm red laser or a special type of lens? Any suggestion will be highly appreciated.

Thank in advance

A 635 nm laser would appear brighter to the human eye than a 650 nm one - even at the same power level. So it's possible that the gun you saw had been modified. Or it could be that the laser in your gun has gotten weak. Do you have a power meter? If so, you can check both guns. If you can get the two guns side by side, the color difference between 650 nm and 635 nm will be apparent.

Original Q-Zar laser tag guns used to have HeNe tubes in them (632.8 nm for the red guns, and 543 nm for the green guns), but since those were fragile and tended to fail, they replaced all the HeNe tubes with diode lasers. Not sure of the wavelength they used for red though. (My guess would be 650 or longer though, due to the high cost of a 635 nm diode back then.)

dry ice? beam isnt very visible unless you are looking towards the source of the beam, and it still needs to be fairly dark. if you want to see the beam easily youll need a fog machine or something for them. im not sure what type of setup you have for laser tag, if its some sort of standard thing or not, but dark with uv lights and glow in the dark paint on object corners so no retards crack their skulls while running around would be the best way to go. even if you were to put stronger lasers in the guns the beam wouldnt be much more visible with/without the smoke. theyll be relatively the same.

Hi:

Many thanks for your answers. Our system is Quasar, a new version of Q-Zar. As far as I know we are using 650nm diode 1mw lasers. But I don´t know what type of laser my competitor is using (the label said 1mw too)

I must suppose that the difference come from less NM and may be more MW. There is something I must to check with the lens, to do it more visible?

Thanks again

the dot represents the shape of the beam. if you have a nice fine small dot then the beam is exactly the way it should be. if the dot is about the same size at a distance as it is close up then its focused the way it should be. the dot should only be a few millimeters in diameter.

you need to have particles in the air for the beam to be visible. cigar smoke, fog, incense, dust, anything like that.

Normally in laser tag they have fog in the air so im sure just a simple 5mw red module would be alot brighter, one from aixis might be just fine.

...lazer... ;D ;D ;D

Yea but they're not allowed to go over 1mW.Whatever darkness or fog settings you have, or plan on getting, I would still stick them with 1mW green lasers if I had the posibility.It's still gonna greatly improve the visibility.

Things · Feb 5, 2008

Yep, if possible, stick a 1mw green laser in them, then they will be ALOT brighter and cooler than red.

Axel · Feb 5, 2008

Ok. Thanks for your answers. I will try a green laser and a 635nm red laser. But, in any case, there is a way to get more visibility of the laser beam?. For example, using a specific optics to increase diameter of the beam?

smaller diameter should equal a brighter beam

Things · Feb 6, 2008

Once you get a green laser, i don't think you will need anything to enahnce the beam, excpet for some fog, a green laser will stand out HEAPS more than a red.

They probably dont put greens in them because they are 100s of times more expensive than a 1 mW red.

Things · Feb 6, 2008

Yep, thats true. If they weren't, youd see green ones all over the place!

spyrorocks · Feb 6, 2008

Green is about 4x more visible than red, you would blow away your competition in terms of laser visibility with a 1mw green and some fog.

Axel · Feb 7, 2008

Thanks for your help. How can i enhance the diameter of a laser beam?

wooooooolazer · Feb 8, 2008

Why would you want to? The smaller diamter the brighter the beam would be.

..lazer.. ;D ;D ;D
