The main purposes of the study are to investigate the potential of rotary ultrasonic machining (RUM) process to core drill Neodymium Doped Yttrium Aluminum Garnet (Nd:YAG) laser crystal material, and to study the effect of lapping and polishing parameters on the surface finish of the machined end faces of Nd:YAG laser rods.

Yttrium aluminium garnet - chemeurope.com

Yttrium aluminium garnet (YAG, Y 3 Al 5 O 12) is a synthetic crystalline material of the garnet group. It is also one of three phases of the yttria-aluminum composite, the other two being yttrium aluminum monoclinic (YAM) and yttrium aluminum perovskite (YAP). YAG is commonly used as a host material in various solid-state lasers.

Yttrium aluminium garnet - Wikipedia

Yttrium aluminium garnet (YAG, Y 3 Al 5 O 12) is a synthetic crystalline material of the garnet group. It is a cubic yttrium aluminium oxide phase, with other examples being YAlO 3 (YAP) in a hexagonal or an orthorhombic, perovskite-like form, and the monoclinic Y 4 Al 2 O 9 (YAM).. YAG, like garnet and sapphire, has no uses as a laser medium when pure.However, after being doped with an ...
