The wavelength of an infrared laser typically ranges from approximately 700 nanometers (nm) to 1 millimeter (mm).
Infrared (IR) light sits on the electromagnetic spectrum between visible light and microwaves. The precise wavelength determines the specific classification within the infrared spectrum.
Here's a breakdown:
- Near-Infrared: 800 nm - 2,500 nm. This region is closest to visible light.
- Mid-Infrared: Approximately 2,500 nm - 50,000 nm (50 μm).
- Far-Infrared: Approximately 50,000 nm (50 μm) - 1,000,000 nm (1 mm).
Because "infrared laser" is a general term, specifying the exact wavelength requires more context about the specific laser type and its intended application. Different infrared lasers are engineered to emit light at different points within this broad range, allowing for tailored uses in various fields like telecommunications, remote sensing, and medical applications.
