Abstract

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.

Description

technical field [0001] The invention relates to the technical field of solid lasers, in particular to an optically pumped on-chip solid laser. Background technique [0002] Solid-state lasers have the advantages of stable wavelength, high output power, and good reliability. Currently, one of the development trends of solid-state lasers is monolithic. Compared with discrete component solid-state lasers, monolithic integrated solid-state lasers have smaller volume, higher integration, higher optical energy density and lower laser oscillation threshold, and smaller resonant cavity size and higher wavelength stability. One type of monolithic integrated solid-state laser is made of a single crystal in free space. A typical example is the monolithic integrated neodymium-doped YAG (yttrium aluminum garnet) based on a non-planar ring cavity (NPRO) proposed by Stanford University in 1984. ) solid-state laser solution, the resonant cavity of the laser is contained in a whole piece o...
