Heatsink help

Hello i am making a 3mode lab style 445nm laser. But i have a problem with the heatsink. The base of my project is plexi-glass. i am also driving the diode at about 1,2Amps so it will be putting out on high mode 1,1...W. I want a heatsink for under 15usd that can cool it for at least 60 seconds without making any problems to the diode. Also the diode is already pressed in an aixiz module.
Any help pls ???

Here's some some help, although not the kind you wanted:
One thread in the appropriate section is ENOUGH!

Posting the same thread in different subforums is bad forum etiquette.:twak:

I did that because i wanted to get as much opinions us possible. :beer:

Please don't post multiple threads of the same thing. I have merged the others into this one.

Pls read the previous posts before writing a reply !!!!

I told to anselm that i did that because i want to get as much opinions as i can !

Instead of telling me what to do can you help me with my problem ??

just FYI, posting multiple threads with the same content is a violation of forum rules and it IS ban-worthy. ONE thread is enough for collecting as much opinions as you can !
