The planar waveguide architectures design with a Nd:YAG core and introduce the ASE suppression material Sm:YAg as claddings. The pump light input uses wedge angle configuration to get corner-pumped Zi
Compare with glass optical waveguides, the crystal fiber waveguide adopted rare earth ion doped YAG crystals as core and cladding, which has higher thermal conductivity and can greatly increase the up
