I can help with your Laser questions

[Lasernerd]

Just ask !!
I have the complete manual with me..
not mod questions or how to fix
Just the legal stuff
Moderators you can make this sticky if you want

ok,
something I've been wondering:

What does a termination point mean in technical terms?

The surface upon which a beam strikes and then stops.

[Lasernerd]

Each Laser demonstration of the "Laser Light Show" thats what its called when lasers over 5mw`s are used for the public.
You will describe the show and the laser operator will choose the proper Termination either by beam blocks or a proper means of not letting any radiation beyond that point

This how we file our "Laser Light Show" reports


A solid barn can be filed as a termination point A rock wall
A brick structure the same.. Water,trees,sky,fog.clouds are not termination points these are considered un terminated "Laser Light Shows"
We laser show operators have several pages of diagrams,descriptions we must file 30 days in advance!
If they see a problem we get a notification to stop and re design...
Un terminated laser shows have been basicly stopped thanks to the nit wits that have done extreme damage to our industry

Very good question Kongfuchicken!
Does the above help?

[kongfuchicken]

yep...
thx

Hi,
is it possible to see the beam of a 100mWatt red (635nm) Laser without any fog, an with how many mWatt green Laser i can compare it ?

[sharkeeper]

I have used a 40mW HeNe and the beam is not nearly as visible as say a 5mW 532 DPSS.

It takes a lot of red to dazzle.

Cheers!

If you are refering to the aixis laser it is 650nm but whether it is visibe or not, im not sure, i will buy one next month and find out!!

[Lasernerd]

If it is 650nm the beam is barely visible till particulate is added to the air

[Wyvern]

even at 100mW?

[Arni]

I can't decide me. Buy or not buy. 100,-$ is really cheap for 100 mWatt, but if i cant see the beam good .....

a few minutes ago i was sitting on the toilet and have a great idea. I put the red one a a green laser in a small case and i have a two colour powerfull Laserpointer. And with a semibermeable mirror i can make a orange Laserbeam. I think i must buy it.

[Wyvern]

i have some of the 10mw ones from there and you cant see the beam but hell is that spot bright, its about the same as a <5mw green maybe a bit less, and that was dirt cheap.
i'll tell you what, i will buy one next month and tell you what it is like, then you can make an informed decision on whether to buy one or not

I have the Poloroid 200mw 650nm unit yes the spot is very bright
but the beam is so crimson red it is just hard to see.
now the 635nm units they are more of a orangish color but show up way better

[greg_in_canada]

Is it legal (in the US) to project beams (lines/fans) into
crowds, like I've seen in pictures from dance clubs
and rock concerts?

If so, I assume there has to be some sort of kill
mechanism in case the beam stops moving.

WAIT... Are you telling me that it is possible to see a laser beam through the air without the help of fog or other particles?

[Lasernerd]

There always is dust in the air unless in a clean room
