LED is a type of focused light source. A diode is a light emitting circuit found in all lasers. All LED lasers have diodes that only permit light and energy to flow in one direction in a concentrated beam. The lasers cause this energy flow by their manipulation of electrons.

The laser LED is called laser diode. Get laser LED here.

An LED laser is a semi-conductor light source, which means the LED laser light source is formed by bringing two slightly different materials close together to form a positive-negative (PN) junction. The positive side, the anode, is created through an absence of electrons and the corresponding holes from this absence. The negative side, the cathode, contains an influx of electrons. The joining of the electrons into the holes creates the light.
