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.

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

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.
