What is better for burning, 532nm green laser or a 405nm blue?

[c1andestine]

Both of these lasers use the exact same "Laser 303" model, are both "5mW" & use the same battery; essentially, the only difference is the wavelength & therefore the colour. Which one would be better for burning by focusing the light?

Hi,
I see you didn't post in the welcome section first . Do that and tell us a little about your self. Folks here might be willing to help .

At 5mw "eye safe" you wont burn anything.
As a general rule both 532 and 405 are underrated on pointers.
They are totally different types of lasers, one is a diode and one is DPSS.
A cheap DPSS usually doesn't have much to block the IR, so output is invisible, higher and more dangerous.
Most common 405nm diodes are better at focusing, so tighter beam and better burning. But are not nearly as visible as a 532
Get yourself some goggles before getting something that burns, unless you want it to include your eyeballs.
