How do you use a laser pointer to burn through things?

I mean things like paper. Not concrete.

'laser pointers' generally are the small <5mW pointers you can get everywhere. Burning lasers are in the 100-1000 mW range - they need focussing and are designed to put out that much power from the get-go. www.dealextreme.com has a red burning 200mW laser for about 40 bucks.
