Help with laser beam dump please!

So I've been browsing and looking at all of your laser beam *****, to which they look awesome! The only problem I've come around is the highest laser I've seen used on them is a 1W 532 nm laser.

I just ordered this

I was wondering, where did you guys get your beam *****? And what is one I can use with this particular laser. My fear is that the laser I have will get too hot for a lot of the beam ***** I've seen.

Incase you didn't click the link, here is a description
1.8W A-Type M140 445nm Blue Diode in Copper Module W/Leads & Three Element Glass Lens

Thick piece of aluminum painted black, job done. I just use whatever I have on hand that won't burn - usually something metal, like a big heatsink (Black anodized in this case), or an old computer that's lying around.

As I said, just use something dark in colour that won't burn or catch fire.

I use a rock. :na:

If you would've got it off his shop, would've probably been cheaper :/

I often use a cinder block, you don't want anything reflective.
