Introduction to High Power LED Lasers

High power LED lasers are a type of solid-state laser that utilizes light-emitting diodes (LEDs) as the light source. These lasers offer several benefits, including high efficiency, compact size, and low cost. The term “high power” refers to the ability of these lasers to produce a significant amount of light output, typically ranging from several watts to kilowatts.

How High Power LED Lasers Work

High power LED lasers operate on the principle of stimulated emission, where an electron transitions from a higher energy level to a lower energy level, emitting a photon in the process. This process is repeated numerous times, resulting in the amplification of light. The key components of a high power LED laser include the LED light source, a gain medium, and an optical cavity.

The LED light source emits light at a specific wavelength, which is then directed into the gain medium. The gain medium is a material that can amplify the light by absorbing and re-emitting photons. The optical cavity consists of two mirrors that reflect the light back and forth, allowing for the amplification process to occur. As the light travels through the gain medium, it gains intensity, resulting in a high power laser output.
