I recommend Lazerer laser + Purchase a power certificate
Here's some of their violet lasers, and compare their prices to WL ;)
Violet Laser Pointer
And 100mW wouldn't burn very well..
2 Watt is really dangerous...
There was this thread about 2watt blue lasers, you should read it

Wait wait wait tell us some more about your laser.
1. From where did you buy it?
2. How much did it cost?
3. Is it your first laser?
4. Do you have safety goggles?
