Welcome Mathew!
What are your interests in lasers? Building them? Buying them? Reading about the gas? Hene, argon ion, ArKr? Soo much to explore.
If you update your location that would help and don't forget to read the stickies.

As DWU already said, you should probably add your location. It doesn't have to be exact, just add your country and state/province/region. It will allow other members to help you with the laser laws for your country.
Welcome to the forum.
Where are you from as that can determine if certain things can be sent to you or not.
Do you have any lasers now? If so, what are some of them?
Please poke around and see all the great stuff in the world of lasers. Be sure to use the white search bar at the bottom of the page as there is a wealth of information to see here.
Remember to get proper safety laser goggles for the wavelength of your laser if it is over 5mW.
Enjoy, have fun and most importantly be safe.
