hello

Hello I am Imran from Trinidad and Tobago. Have been here since couple of months. Since my childhood I was very attracted towards lasers.
I love this site and I have purchased Arcane from MrJoker. and I am enjoying this very very much.
as everybody know there is no end to the dreams. now I am really eager to build my own laser. I have been reading all the tutorials and I am very excited to build one laser for which I request everybody's help.
Thank you

Re: hello

Welcome! Coherent light is amazing, I agree! It is one of the most awesome things I've seen at night when such a tight beam of light shoots upward into the heavens far beyond what anything else can be seen to do. It's also like being able to see light from the side, although merely a reflection from things in the air. Just don't shoot yourself in the eye
