This page discusses different types of lasers, including solid-state lasers, gas lasers, excimer lasers, dye lasers, and other types. There are numerous laser types available, each suited for various applications. The laser types depend on the medium used. Here’s a breakdown based on the medium:

Laser Types

  • Solid-State Laser: These lasers emit infrared light, typically at a wavelength of 1.064 micrometers.

  • Gas Laser: Gas lasers often have a primary output of visible red light. CO2 gas lasers emit energy in the far-infrared region, specifically at a wavelength of 10.6 micrometers. They are often used to cut hard materials.

  • Excimer Laser: Excimer lasers produce light in the ultraviolet range.

  • Dye Laser: This type of laser is tunable over a broad range of wavelengths, making it versatile for different applications.

  • Semiconductor Laser: Semiconductor lasers are very small and use low power. They are commonly used as writing sources in devices like laser printers, CD players, and DVD players.
