Awesome, I'd love to see any such device that you end up building. I don't know a ton about lasers but your explanation makes sense.
Personally I'm still getting my undergraduate degree (physics and aerospace engineering), but I hope to go to graduate school for physics in the next few years. So I don't yet have a well defined specialization.
Just keep going, keep studying, working hard, even when it's a pain in the arse. Always believe in yourself, I didnt come from a great background, but with self belief and determination anything is possible man.
You'll find your favoured area and you will excel, keep doing your thing man.
If I can ever give you advice you know where to find me. I'm always happy to help good people.
Rock on dude!
