What Does an Infrared Laser Do?

Infrared lasers are devices that emit light through the process of optical amplification based on the stimulated emission of electromagnetic radiation. The term infrared refers to the region of the electromagnetic spectrum that lies beyond the visible spectrum, with wavelengths longer than visible light but shorter than microwaves. Infrared lasers operate in wavelengths from about 700 nanometers (nm) to about 1 millimeter (mm), which means they emit light that is not visible to the human eye.

Applications of Infrared Lasers

Infrared lasers have a wide range of applications across various fields due to their unique properties. Some of the key applications include:

  • Medical Treatments: Used in various medical procedures, including eye surgery, dental procedures, and dermatology for skin treatments.
  • Telecommunications: Integral in fiber-optic communication systems for transmitting data over long distances with high speed and low loss.
  • Military and Defense: Employed in targeting, range-finding, and missile guidance systems. Infrared lasers are also used in countermeasure systems against heat-seeking missiles.
  • Industrial Processing: Utilized in cutting, welding, and material processing for their precision and ability to deliver high power.
  • Scientific Research: Applied in spectroscopy for studying the properties of substances and in various types of sensing and measurement applications.

Infrared lasers are valued for their ability to deliver precise and controlled energy, making them indispensable in many technological and scientific fields.
