What Is a YAG Crystal?
A YAG crystal, short for yttrium aluminum garnet, is a synthetic crystal that serves as an essential component in lasers and optical devices.
Its luminescent properties are harnessed by doping the crystal with rare earth elements and subjecting it to excitation, which in turn generates luminescence. This luminescence is amplified within a resonator, producing coherent laser light.
YAG crystals find applications across a wide array of fields including medical, materials processing, precision measurement, and communication technologies. In the medical sector, they are integral to laser-based surgical and therapeutic devices. For materials processing, they facilitate cutting and welding operations. In the realm of measurement, they enable high-precision assessments, while in communication, they contribute to the efficiency and reliability of systems. Beyond their role in laser generation, YAG crystals are also prized as optical components, finding use in lenses, prisms, filters, and various other optical instruments.
