As for the laser diode, I assume you don't need to modulate it. That's a
whole other beastie.
If not, IMO, you are better off getting a laser diode module with the
power supply and regulation etc. already done for you.
As for the clicky wheel. Try one of those Chinese parts importer search
engines if you need them in quantity.

I have  source for laser modules bookmarked here somewhere...
I'm on my way out the door to meet my wife for dinner, it's my birthday.
Not something I'm wishing to celebrate much anymore. Getting to that
age. I'll have a look tonight or tomorrow though OK?

Later,
Happy first day of winter, winter solstice, birthday, holidays.... everyone!
