On-chip solid laser of optical pump

The invention discloses an optical pumping on-chip solid laser, which comprises a solid gain medium substrate and a laser construction structure, and is characterized in that the laser construction structure is positioned above the solid gain medium substrate; the laser construction structure comprises a resonant cavity, a pump light input structure and a signal light output structure; the resonant cavity is located between the pump light input structure and the signal light output structure, and the resonant cavity abuts against or is in clearance fit with the solid gain medium substrate. The optical pumping on-chip solid laser has the advantages of being small in device size, small in optical mode size, low in threshold value, high in stability, high in integration degree, flexible in preparation mode and the like. 本发明公开了一种光泵浦的片上固体激光器，包括固体增益介质基片、激光构建结构，所述激光构建结构位于所述固体增益介质基片上方；所述激光构建结构包括谐振腔、泵浦光输入结构、信号光输出结构；所述谐振腔位于所述泵浦光输入结构和所述信号光输出结构之间，所述谐振腔与所述固体增益介质基片抵接或间隙配合。本发明提出的光泵浦的片上固体激光器具有装置尺寸小、光模式尺寸小、阈值低、稳定性高、集成度高、制备方式灵
