Buy yourself a laser pen. It is much cheaper and better working than make one yourself.

what type of laser do you want to build, a solid state laser, a gas laser or a semi-conducting laser?
Here's a site that shows you how to build a nitrogen based laser. Just realize that building a laser is not some beginning science project and you really need to study up on it to understand the subject.

Building a laser from scratch takes an infinite amount of precision and patience. You can buy laser diodes and build your own but even they are "notoriously fussy" (per ref. 1). Also check out ref 1's link to the Sam Goldwasser laser info (ref. 2).

If you want to use the laser, rather than learn about the physics of lasers, every CD and DVD player has an operating laser measurement system in it.

I will put this as easy as I can your eyes are worth more than twenty thousand "experiments" with laser diodes - Safety first !! if you are a novice and do not know what you are doing expect to come out of this with a serious injury.
Bottom line do something else that interests you.
