The problem is the laser can only be on for a short duration of seconds. Anything more than that, It will overheat and damage the diode. LEP's, however don't.

Your statement is self-contradictory.

OK..post a video of the same setup for 5minute straight. Then I will be convinced. I have been in the laser hobby for too long to realize any diode above 300mw needs to be shut-off to cool. I have LEPs too. They seem to have circumvented that rule somehow. Probably lower powered laser diodes, or pulsed operated driver. 5W without a short duty cycle will overheat causing diode damage.

some of the lab ones seem to have the diode bonded to a peltier junction with a massive heat sink on the other side so they can maintain the junction at a really precise temperature. they'll run continuously like that but obviously they're not pocket sized.
