Reply to comment by flabberghaster in If light is just electromagnetic waves, and color is just different frequencies of light, and we can make radio waves at arbitrary frequencies, why can't we create visible light of arbitrary pure colors? by flabberghaster
I don't know a lot about lasers and orientation!
But yeah, tunable lasers cost a lot of money. Like, price-not-listed-call-us-for-a-quote prices. As I understand, argon ion lasers could emit most of the frequency spectrum.
Definitely going to revisit this thread if I happen to run into someone who knows more lol
