Infrared lasers are a type of laser that emit light in the infrared region of the electromagnetic spectrum, typically with wavelengths between 700 nm and 1 mm. These lasers are used in a wide range of applications, including communications, spectroscopy, remote sensing, and material processing. Infrared lasers are particularly useful for detecting and analyzing materials that interact strongly with infrared light, such as organic molecules or certain types of gases. They are also commonly used in medical applications, such as surgery and dermatology.
