Hmm,

Some googlefu brings up some decent results, but I'll be sure to ask where the old man got his from.

It's a good thing too. Because if a lasers beam was visible in outer space, we would all be sleeping with our pillow over the head. The stars, as well as our sun would have radiant beams that would not allow for darkness, ever. :D

Given all this, a laser beam would be invisible in outer space even if it were 1TW or 1PW or even more than that.

Actually the brightness would not increase one bit, it just would be distributed differently.

Just an idea, but .....

..... what about using a fluorescent fluid in a smoke machine, with a BR pointer ?

Can make your 25mW pointer beam looks like an 1 W blue one, LOL !

Wow Flo fluid, if that stuff were to stick to what ever it settled on, it would remind me of my days going into head shops. All thoses pretty colors. Take me back Bob Marley WOOOOOOOOOOO

LOL ..... well, they sell fluo fluids in green and blue for soap bubbles, so i imagine there's not so far for find something similar also for fog machines, if they really want ..... :D

(better for outside use, anyway :p)

@himln9,,, on the topic of adding something to the "fog juice", a family member of mine sugested i try a little laundry detergent because of the added phosphorus. I have not tried this yet. but it is an idea.

To get beams to be visible they really need something in the air to reflect off... but this can be very subtle. Even if you smoked a cigarette in a room hours ago, that will still enhance visibility of laser beams, even though you cannot see the smoke as such anymore.

Compare it to weahter conditions: a visibility of 1 km wont affect anything you do (unless flying aircraft or such), but it will increase laser beam visibility greatly over the 'standard' >10km visibility conditions.

Well, DIY smoke fluids are not the better choice, but i think that, at least, one thing can be tried ..... finding some fluoresceine in some pharmacies, and adding VERY FEW of it to the smoke fluid (like, half gram in 100 CC, or also less, for the first trial), after having melted it in water, if the experiment is done OUTSIDE HOME, i think it's safe enough ..... the purpose is to see if the fluoresceine is vaporized with the rest of the fluid, or if just become decomposed and burned from the heater of the fog machine (cause, ofcourse, if it becomes burned, there's no worth to add it to the fluid)

Maybe ultrasonic hazers can do a better work, but haze is usually not the maximum, for these applications, and left more residuals around (and last shorter, too)

Just remember that, for safety, always try these experiments outside, and breath the smoke the less possible :p

Also, this wasn't mentioned but can make a small difference. If the beam diameter is smaller then the beam will be brighter. If you are pointing longer distances then you want to have better divergence for a sharper beam.
