Have somebody build a He-Ne Laser on himself ? Does that work ? Or do you buy your Lasers ? :-?
 





It's very possible! I'm starting on my first diy gas laser very soon. Give SAMs FAQ a good read before you jump in. I would start by building a CO2 laser because the gas has a ton of gain and just WANTS to lase. they are very forgiving when it comes to gas pressure which is very hard to get just perfect on other lasers.

If you plan on building a gas laser, do it for the fun and experience of the project. If you're looking to build a better quality or cheaper laser than one you can buy, you'll be disappointed! At least when it comes to HeNe lasers. A sealed hene built by a laser company will last thousands of hours. Most diy HeNe's are a 'flowing gas' design (or at least have a built in reusable gas fill valve, and a vacuum valve at the other end) because a diy sealed tube laser will have a pretty short life... Maybe 100 hours if you're really really lucky.
 
GG pretty much summed it up. If want to try something super simple you can always build a TEA nitrogen laser, it's easily the most inexpensive gas laser to DIY.
 
the TEA nitrogene laser( i have found a good link, but not allowed to post :P)

looks interesting and easy to build, this could be the perfect start into the material
 
Yeah he is my main teacher for laser systems as well as vacuum and thin film systems. He is a very strange man... Good teacher though.
 
nice.. you`re study laser physic , i´m thinking to do that too after school it´s a very interesting theme, what can you say about it, is it difficulty? what you must
can to study that ?

thanks for each answer..
 
It isn't very easy. It's about the same difficulty of any other physics program. I would recommend you take physics and chemistry, as well as calculus if possible in high school to get started.
