Hey everyone.
Name is Leon, from Stockholm, sweden.

A little about myself;
I'm 21 years old, senior IT technician for a company, amateur photographer and ex-progamer.
I'm rather experienced with electronics, I've been working on personal (for fun) projects since i've been around 16, mostly Tela coils and other high voltage related things.
I've came across the world of lasers since a couple of years now, though lacking the necessary knowledge, I've never really dared to do anything myself.
My interest in it has been re-ignited by some youtube videos only lately, and I've finally decided to sign up in this forum.
Expect to see many dumb questions from me, as I mentioned below, I literally know nothing about lasers, besides the electronics behind them.

Hoping to get along with everyone, and thanks for reading!

welcome and nice intro. would you mind adding in your location?
i hoped you've read all the stickies...
before messing around with any high power laser get yourself a pair of goggles and sunglasses won't protect your eyes from laser.

Yep! I've read them, and they seem like standard forum rules/common sense to me^^.
Anyway, fortunately, messing with high voltages for years taught me to treat that kind of things with the right respect, though I do have a question.
The main reason why I've never messed with lasers before is that I've been online, and saw an huge variety of laser goggles, and most people say that they're made for a specific wavelength, how can i know what wavelength a certain laser is?
Also, How can I know what goggles to trust? I've seen an huge range of prices.
Thanks!

Colour.
Laser colour equals wavelength, so you buy a pair of goggles covering/within the range of laser wavelength you're using.
Also you need to make sure the goggles/glasses have enough protection for the laser power you're using.
This is expressed in O.D (Optical Density) rating.

As stated Eagle Pair by Survival Laser is highly recommended.
See here: Safety

This pair below is the usual ones used for Green (520nm and 532nm) and Blue Lasers (around 450nm) .
Eagle Pair® 190-540nm Standard Laser Safety Goggles

This pair below is usually used for Red Lasers (around 638nm)
Eagle Pair® 190-400nm & 580-760nm Laser Safety Goggles

Thanks a lot!

I'll surely look into those.
Another thing, though it's probably a good general rule to use goggles when operating any kind of laser, around what power do they become strictly necessary?
I heard that you should be wearing glasses with any laser around 15mW or above, is that right?

Hey Leon! Welcome to the forums!

That white search bar below here is an amazing resource! If you have a question try using that first to search a few threads before asking. :D (Not saying this in reference to your goggle question, this is YOUR thread, you can ask what you'd like) ;)

It's too bad that when I hear about or see your city I automatically think of Stockholm Syndrome. :/ But hey! At least it puts your city on the map, sort of! :)

Take care,
Nate.

In that case I guess I'm gonna have you to come over, so you can remember my city for something else :D
Jokes aside, I've managed to find some stores located in Europe, and they're selling their models of goggles, how do I know if they're good as well?

Hello Unleashed, you should add your location to your profile so it shows under your name, no one will know or remember you're from Sweden from just this thread. Here is one store in the U.K. That members here buy from: OdicForce and we have a member in Norway that sells lasers in the form of a parts bundle that requires some minimal assembly: BitLasers We have at least one other active member in your country but I can't remember who just now. New members are invited to also post here: http://laserpointerforums.com/f57/countries-lpf-where-you-94536.html I have been attempting to maintain a list of countries along with state/province/territory of the active members here. Welcome to LPF.

Hey, squared, thank you a lot.
I found that site you linked bitlasers quite interesting!
For the most part, I saw there's a section for safety goggles Accessories , and they're rather cheap too!
Why are those less than 10$, while the majority of the ones I saw in other sites are around 50$?

There are plenty of really cheap ones made in China, some of them are good and some are not. The expensive ones are certified laser safety glasses and are tested and known to meet certain standards. Some of the cheap ones don't measure up to standards and aren't officially certified laser safety glasses but many of them are good at least up to a certain power, some of them have been tested by members here.
