A Specific Type of Laser with Many Applications
To understand an Nd:YAG laser, it helps to know the basic elements. ‘Nd:YAG’ stands for ‘Neodymium-doped Yttrium Aluminum Garnet,’ and ‘LASER’ is an acronym for ‘Light Amplification by Stimulated Emission of Radiation.’ In this type of laser, the atoms in an Nd:YAG crystal are excited by a flashlamp, and the crystal produces amplified light that travels at a specific wavelength – 1064 nm.
The 1064 nm wavelength is outside of the visible spectrum, so the light is invisible and within the infrared range. This wavelength of light has many practical applications.
This type of laser is used for a variety of medical, dental, manufacturing, military, automotive, and scientific purposes. The differences between types of Nd:YAG lasers depends on other factors of the laser system – the amount of power delivered to the flashlamp and the pulse width of the laser output.
