Diode lasers operating at 810-nm to 1064-nm are part of which section of the electromagnetic spectrum?

• A. Ultraviolet nonionizing
• B. Visible nonionizing
• C. Visible infrared
• D. Infrared nonionizing

Answer: (D)

Diode lasers that operate in the wavelength range of 810 nm to 1064 nm fall within the infrared portion of the electromagnetic spectrum. Specifically, this region is categorized as nonionizing radiation, meaning that it does not carry enough energy to ionize atoms or molecules. The infrared spectrum typically covers wavelengths from about 700 nm to 1 mm. Diode lasers, particularly in the specified range, are commonly used in various applications, including therapeutic uses in medicine and aesthetic procedures, due to their ability to penetrate the skin and target underlying tissues without causing damage to the outer layers. This therapeutic benefit reinforces their classification as nonionizing, as opposed to ultraviolet light, which can be ionizing and harmful at lower wavelengths.
