1. A method of assembling of a gyrolaser having a main body including a cavity, the method comprising:
pressing a first surface of a mirror against a second surface bordering an opening of the main body so as to create molecular bonds at an interface between the mirror and the main body to fix them one to the other by molecular adhesion, the main body and the mirror being made of materials that are compatible with bonding by molecular adhesion, and
heating the interface to consolidate the molecular bonds created at the interface, consolidation comprising emitting a power laser beam towards an impact point forming a portion of an outline of the interface, and moving the impact point along the whole outline of the interface, consolidation being performed after at least one electrode has been cold bonded onto the main body.
