Other Lab Garnets


      Yttrium Aluminum Garnet (YAG), Gadolinium Gallium Garnet (GGG), Lutetium Aluminum Garnet (LuAG), and Gadolinium Aluminum Gallium Garnet (GAGG) are synthetic garnet crystals each known for their distinctive properties and applications, particularly in the fields of optics and photonics. YAG, renowned for its thermal and optical stability, serves as a versatile medium in laser technology. When doped with neodymium (Nd:YAG), it is widely used in medical lasers, industrial cutting and engraving, and as a pump source for other laser types. YAG's durability and efficiency in high-temperature environments make it an ideal candidate for such diverse applications. GGG crystals, on the other hand, are primarily used as substrates for magneto-optical films and in optical isolators due to their excellent optical transparency and compatibility with various doping elements. GGG's unique magnetic properties also make it suitable for use in scientific research, particularly in studies related to magnetic phenomena.ย 

      Neodymium-doped YAG (Nd:YAG) is the most well-known, generating infrared laser light primarily used in medical procedures, manufacturing, and as a pump source for other lasers. Erbium-doped YAG (Er:YAG) produces a wavelength that is highly absorbed by water, making it ideal for medical applications involving skin and dental surgery. Ytterbium-doped YAG (Yb:YAG) offers advantages in high-power applications due to its high efficiency and low quantum defect. Chromium-doped YAG (Cr:YAG) is used as a passive Q-switch in laser systems, creating high-power laser pulses by modulating the intracavity laser beam.
