is there a real basic online laser optics course?

I watched the beginner soldering series of videos. It was great. I'm starting into this laser hobby completely clueless pretty much. I started just liking the concept of burning stuff but I am starting to think past the normal 'i wanna burn the neighbors cat' typical thinking that im sure we all dont admit to.

Anyway....

So I have several pointers on order (waiting on shipping) and I am thinking about putting together a green labby. This would be some sort of rail mount setup (although I dont have one picked out at the moment).

But I'm sort of clueless as to the roundy clear jobbies the light beam goes through (lenses ).

Is there a online real basic optics course like the beginner soldering videos?
