Why are most 445nm lasers >1W?

Hello everyone, I'm planning on building a handheld laser with the 1.8W 445nm A-Type M140 so i can burn some holes in random useless items.

I do have eye protection, here is the link to the ones I've purchased:Eaglepair OD5+ 190-540nm&800-1700nm Glasses

In my search for the "ultimate burning device" (while also keeping a budget), I noticed that most 445nm-450nm diodes have an output >1W, with the exception of some of the ~80mW OSRAM PL450B's.

Does anyone knows why most 445nm diodes are at such a high rating and what they are used for in labs and industry?

Also, does anyone know of any cool applications of a 1.8W 445mn laser besides melting my enemies? :lasergun:

Note: my enemies are pieces of scrap paper and electrical tape, not real people :p
