Line Laser Diode
導入
A line laser diode is a type of laser diode that emits a laser beam in the form of a straight line. It is commonly used in various applications like 3D printing, barcode scanning, laser leveling, and alignment systems. This article will delve into the functioning of a line laser diode and its unique characteristics.
Functioning
A line laser diode operates based on the principle of stimulated emission, amplifying light through the process of optical amplification. It consists of a semiconductor material, typically gallium arsenide or gallium nitride, which is doped to create a p-n junction. When an electric current is applied to this junction, it causes the emission of photons, resulting in laser light.
The emitted laser light is then shaped into a line by a cylindrical lens. This lens has a unique focusing property that converts the diverging laser beam into a narrow line. The lens’s design allows it to maximize the power and visibility of the line while minimizing divergence.
