In this article, we will delve into the world of low power IR laser technology, exploring its working principles, applications, advantages, and challenges in the industry.

Introduction to Low Power IR Laser Technology

Low power IR laser technology refers to the use of infrared lasers with output powers ranging from a few milliwatts to a few watts. These lasers are characterized by their low energy output, which makes them suitable for various applications in medicine, industry, and consumer electronics. The infrared spectrum spans from 700 nm to 1 mm, with different regions being used for specific applications. The working principle of a low power IR laser is based on the stimulated emission of photons. This process involves the excitation of electrons in a gain medium, such as a crystal, gas, or dye, to a higher energy state. When these electrons return to their ground state, they release photons with energy corresponding to the energy difference between the two states. The emitted photons are then amplified through the gain medium, resulting in a coherent beam of light.
