Summary:A method for overcoming parasitic oscillation of an Nd: YAG (neodymium: yttrium aluminum garnet) batten gain medium by coating comprises the following steps: P1, polishing a side surface I, a side surface opposite to the side surface, a side surface II and a side surface opposite to the side surface of an Nd: YAG-based pumping batten to form a good reflecting surface; p2, a parasitic oscillation suppression material Sm: YAG is selected, the doping concentration is larger than 5.0 at%, and the material does not obviously absorb common LD pump light of 700-900 nm; p3, preparing a parasitic oscillation suppression material Sm: YAG to a side surface I, a side surface opposite to the side surface I, a side surface II and a side surface opposite to the side surface II of the Nd: YAG in a coating manner; the mode that the side face of Nd: YAG is plated with Sm: YAG is adopted to suppress parasitic oscillation, the highly-doped Sm: YAG can achieve total reflection of pump light and has a remarkable absorption effect
