1. Introduction
1.1 What is a laser diode
A laser diode, also known as a semiconductor laser or injection laser, is an electrically pumped semiconductor device that generates coherent light. It is a type of laser that is widely used in various fields due to its compact size, high efficiency, and low cost.
1.2 Importance of laser diode 808
Laser diode 808, specifically refers to a laser diode that emits light at a wavelength of 808 nanometers (nm). This specific wavelength has significant applications in various industries, including the medical, cosmetic, and industrial sectors.
2. Working principle of laser diode 808
2.1 Structure of laser diode 808
Laser diode 808 is typically made up of several layers of semiconductor materials, including a P-type layer and an N-type layer. These layers are sandwiched together to form a p-n junction. The active region within the diode is where the laser light is generated.
2.2 Laser diode emission process
When an electric current is applied to the laser diode, it excites the electrons within the active region. As these electrons move from the higher energy state to the lower energy state, they emit photons. The photons then bounce between the reflective surfaces of the diode, forming an intensity of coherent light, resulting in laser emission at 808 nm.
