Okay. I want a laser that has an impressive beam. Any suggestions for a noob like me?
Your OP doesn't make any sense in several directions/ways and is problematical in several ways.
It makes you appear to be reckless, irresponsible---an accident looking to for a place to happen. Nobody will want to help you.
Why would you buy a diode module that you know nothing about nor even how to power or use it or use it safely?
Just a module w. diode is almost useless alone. Is easy to destroy the diode if you don't know what you are doing or why.
See here for for host and heatsink and driver assemblies that are easy to make and have good tutorials: Survival Laser USA Home
High power diodes are not toys--they are very dangerous and can cause serious injury to eyes at the speed of light.
Suggestion #1 is study up on proper operating procedures, laser safety, and always use laser goggles--high output diodes can easily cause permanent ocular damage of blind you faster and more easily than you can imagine--in less than human blink reflex time of 0.25 seconds---zero chance of making any correction one accident is in progress.
