5V 5mW Dot Laser Diode

Description
A laser diode is an optoelectronic device, which converts electrical energy into light energy to produce high-intensity coherent light. In a laser diode, the p-n junction of the semiconductor diode acts as the laser medium or active medium.
This 650nm laser module with TTL is an industrial electronic component used for the industrial testament, Lab, DVD and Blu-ray players, barcode scanners, fiber optic communication equipment and laser printers.
The working of the laser diode is almost similar to the light-emitting diode (LED). 
The main difference between the LED and laser diode is that the LED emits incoherent light whereas the laser diode emits coherent light.
