    Neodymium Doped Yttrium Aluminum Aluminum Garnet(Nd:YAG)Crystal
    
    Neodymium Doped Yttrium Aluminum Garnet-Nd:Y3A15O12(Nd:YAG) with high efficiency, high beam damage threshold and good heat conductivity ,has been applied to 
    activate and sensitize ion so as to enhance the laser output. Therefore, it has been continuous to be the most widely used solid state laser material. At room temperature, it can work in continuous, pulsed and many other modes in which the continuous modes is its most efficient mode whose laser output has reached KW level.
