What does TTL Modulation mean?

wow this is old. i was wondering about that also but isnt there alot of trouble if you dont have clean signal to your diode? im pretty sure a transistor wont muck it up but ive never tried.

Should'a just bought one with TTL. No more costly than those without.

This is a great thread! We probably have enough stickies, but it sure made it easy for me to quickly digest TTL on a laser!

:thanks:
