YAG Crystals

Yttrium Aluminum Garnet (YAG) crystals are widely used in medical, industrial and research applications thanks to their high thermal stability, excellent optical properties and mechanical strength.

MSE Supplies offers a range of high-purity YAG crystals, including:

  • MSE PRO™ YAG crystal lenses
  • Cerium-doped YAG to be used as a scintillator or an LED phosphor
  • Neodymium-doped, holmium-doped and erbium-doped YAG for solid-state laser systems
  • MSE PRO™ YAG phosphors for LED applications

Whether you need doped YAG for laser systems, scintillation detectors or LED phosphors, our PhD-level scientists provide the expert guidance and technical support you need to choose the right crystal for your project. We can tailor our YAG crystals to meet specific performance requirements, including varying dopant concentrations and substrate sizes. Request a quote for custom solutions.

Frequently Asked Questions

What is a YAG crystal?

YAG is yttrium aluminum garnet (Y3Al5O12). It is hard, chemically stable and optically isotropic, which makes it one of the most widely used host crystals for solid-state lasers.

What is the difference between Nd:YAG and Yb:YAG?

Nd:YAG lases at 1064 nm and is usually pumped near 808 nm. It is the most common solid-state laser crystal. Yb:YAG lases at 1030 nm, is pumped near 940 nm, and produces less heat, which suits high-power thin-disk lasers.

What is Ce:YAG used for?

Ce:YAG emits yellow light at around 550 nm. It is used as a scintillator in radiation detectors and as the phosphor that turns blue LED light into white light.

What is Cr4+:YAG used for?

Cr4+:YAG works as a saturable absorber for passive Q-switching of Nd:YAG and Yb:YAG lasers, producing short, high-energy pulses.

How do I choose the doping level?

Higher doping absorbs pump light in a shorter length but adds heat and can reduce efficiency. Nd:YAG is commonly around 1 at%. Match the doping and crystal length to your pump source and laser design.
