am i missing anything? 1 watt laser build

i'm planning to build a 1 watt burning laser for a school project and am looking for some guidance. i need to know if the parts i am planning to use will work together and if there is anything i should know. i plan on using this diode

do i need a heat sink for this build? if so, what is adequate? is there anything i'm missing or not taking into account? this is not my first electronics project, but it is the first time i've used a diode this powerful. i have all the safety equipment already laid out so don't worry about me blinding myself. thank you in advance.

Why did you open an Identical Thread to the one you already
have open...

That is called Spamming the Forum and is frowned upon....
Not a good start.....
