Just out of curiousity, why are there such things as "modes" for a laser?
Does it have to do with the way the laser light is reflected inside the cavity or something?
How come laser DIODE's are called multimode, but don't really have a TEM xx dot type?
What really causes difference mode types in the first place? Specifically Rectangular modes vs. circular?
I know a lot of questions, but I'm curious.
