Beschreibung
Zusammenfassung:	The utility model provides a miniature long-optical-path optical cavity, which comprises optical assemblies, the optical assemblies are arranged at two ends of a shell, and an optical cavity is formed in the shell; the optical assembly comprises a first reflecting mirror and a second reflecting mirror, the first reflecting mirror is a concave reflecting mirror, a light beam incidence hole and a light beam emergence hole are formed in the second reflecting mirror, the first reflecting mirror is installed in the reflecting end cover, and the second reflecting mirror is installed in the transmitting end cover. The reflection end cover and the emission end cover are correspondingly installed at the two ends of the shell through light beam adjusting structures. An information acquisition module is arranged on the transmitting end cover, and an air inlet and outlet structure and a heating structure are arranged on the shell. The optical fiber laser is simple in overall structure, easy to process and assemble, and l
