Hey , there .
I just got myself a 445nm laser and I just realized the beam output is rectangular.
After a bit of googling , it happens that is called multi-mode laser diode.
And one of its characteristic is a rectangular beam output , or so I read.
However, this got me thinking.
How come we can't make a multi-mode laser diode that can have a circular laser beam output?
For one ,the divergence would be better . (or so I read )
For two , as a result, it would make a much better burning and also much more far reaching.
PS: I'm as green as a leprechaun with regards to laser... so.... if this is a stupid question... don't cave my skull in eh?
