Default Would a 445 diode burn better with corrective lenses?

I was thinking that perhaps with crrective optics, a 445nm laser would burn better when focused.
I'm thinking a 405-G-1 lens with corrective optics might make be the best burner. Am I right?


See, a 445 diode sent through a typical aspherical or aixiz lens has 2 focal points... the fast axis and the slow axis. Both will focus into a "line" at separate distances. Abd because power-density is what allows burning, a shorter line (or more dot-like) spot would have a greater power density. Cylindrical corrective optics, like DrLava has, should allow the beam to become mroe spot-like. However, more optics means more losses in the beam power.

So what is the typical power loss from corrective optics?
With the decrease in power, do the corrective optics still allow burning?
Should I just shut-up and crank up the power?

Sure it would, just ask Dr.Lava
