So yeah, that's basically what I'm wondering. What distinguishes a laser diode from an LED?
Both are diodes that emit light of a specific wavelength when energized.
The light from a laser diode is not focused into a beam without the aid of a lens.
Could someone take one of these bright CREE LEDs, use a lens to focus it's output, and build a "white laser"?
