What is a laser diode?

👉The LASER in Laser Diode is an acronym for 'Light Amplification by Stimulated Emission of Radiation'. It is also referred to as a semiconductor laser and generally abbreviated as LD.

👉Its main feature is high coherency, making it possible to emit light with the same phase and wavelength.

👉Laser oscillation is achieved by amplifying light generated through current injection between two mirrors. Simply put, a laser diode is an LED that amplifies and emits light using reflectors.
