How to make a laser?

[cezar]

I'm new to the world of lasers.. Can someone teach me how to make one?
I've seen videos on youtube made from dvd laser diodes, can someone teach me the steps?
and where to buy cheap parts? Is it possible to buy even if I'm in the philippines?

Welcome to the forum!

Here's a video walk through on making a 100mW violet laser>http://www.youtube.com/watch?v=DVugSGldXZ8

For a burning red laser read around the experiments and mods section, there is a ton of info on building lasers there.

You can also just buy a 200mW red laser with free worldwide shipping for $44 from here> http://www.dealextreme.com/details.dx/sku.11315
