Hello,

Im new to this forum, but have had a couple of lasers (5mw red)
With the new technology and powerful lasers, what do most of you guys/girls use the lasers for?
I mean, its dangerous to shine them on the sky as you can hit a plane of a helicopter and get arrested. Or shine any other place outside as could hit someone and cause eye injury.

I was looking forward to buying a 1w blue laser, but thinking twice.

for me....they are pretty much quantum eye candy.
i bought my first laser (green) to use as a star pointer, i'm an astro-geek too:beer:
 
Pop balloons .. of course !
Well actually a have never done it. I like burning CD cases a lot more.
 
As basic as it sounds, I primarily use my lasers for nothing other than the fact that I enjoy looking at the beam. :)

Depending on wavelength of laser and the method used to produce the light the beam can be thin or thick. If you add a beam expander the beam can be much thicker, but then the beam divergence (how much it spreads out over distance) is greatly reduced.

Comparing two green lasers that I have one is beam expanded and has a 1cm wide beam. The other greens beams are about 1.5mm or so. The strange thing is that the dot will be smaller at a greater distance with the 1cm beam 532nm green than the 1.5mm one if you were to point it a long distance away and look at the dot.

These kinds of things are interesting to me and what makes me like lasers and the hobby. :)

I grow blueberries, and raspberries.
My daughters and I will use the two cheap greens we have , to scare birds off the berries.
Before we tried this, we would only get about half of the fruit and the birds would get the rest.
 
I was also looking forward to making/buying 1 watt blue laser... but doesn't seem like I'd use it a lot. I mean, it'd be awesome to build and make but when it comes down to it... I'd prefer a cool greenie. Although I can't find anything better then DX's module :( anyone know of true 200mw?

I just got 2 200mw on ebay from "laser lands". They claim 10% +/- tolerance.
Both are measuring 150 - 160 on my meter.
I bought a 250mw and it measured 50. (from laserpointerpro)
Buying a lot of this stuff is like going to Vegas.
 
i ordered a 200mW module from techhood on ebay, they where inside the 10% tollerance just by 6mW (LPM'd at 186mW)
 
Thanks everyone for the posts.
I just bought my first powerful green laser, its a 100mw. My next one will be the survivor 1.1mW blue!

lol 1.1mW, just a heads up, ive seen 2 errors in your posts now and you dont quite have the grip on the units of output power.

1mW is 1/1000th of a watt, 1000mW = 1W.

In your first post you say 5W red which i assume is 5mW and your last post is 1.1mW which i assume is 1.1W or 1100mW

Id thought id clear that up for you before it becomes a problem :D

Whoops.
I mean a green at 100mw and will be getting a 1100mw (1.1W) blue!
I'll correct the first post. thanks for pointing out.
 
I'm waiting on my first laser to arrive (just bought one of survival laser's kits with the s4 host), but I entered this hobby with the goal of FINDING reasons to use them. I have a couple activities that can benefit from a "ranged ignition source" ;). But that aside, since the first laser show I attended, I fell in love with them. I'm also a big tech geek who loves building electronics from scratch so one of my eventual goals in learning from this forum is to build the entire thing myself. I've already got a host design drawn up that I need to fire up Autodesk to finalize and machine.
