Understanding Different Laser Wavelengths and Their Applications

Harness the Laser Spectrum

In the realm of technology, lasers stand as a radiant force, unleashing an array of wavelengths that empower groundbreaking applications. Delve into the fascinating world of laser wavelengths and unveil their extraordinary versatility.

A Kaleidoscope of Colors

Laser wavelengths span a vast spectrum, from the near-infrared to the ultraviolet. Each wavelength possesses distinct properties and ouvres a window into unique applications.

Visible Spectrum (400-700 nm)

This vibrant realm encompasses the colors we perceive with our eyes. Green lasers (532 nm) excel in laser pointers and medical treatments, while blue lasers (405 nm) illuminate high-powered lasers in industry and research.

Near-Infrared Spectrum (700-1400 nm)

Invisible to the human eye, these wavelengths penetrate tissues and find use in medical imaging, thermal imaging, and spectroscopy.

Mid-Infrared Spectrum (1400-3000 nm)

Observing vibrational motions, mid-infrared lasers (e.g., 2.0 μm) analyze materials in spectroscopy and imaging applications.

Far-Infrared Spectrum (3000-100,000 nm)

Expanding further, far-infrared lasers (e.g., CO2 lasers) emit at wavelengths measured in tens of micrometers. They are widely employed in industrial cutting, welding, and engraving.
