Abstract
The invention relates to a high-power fiberoptic laser device comprising at least one laser diode (1) capable of transmitting a pump wave, a triggered optical resonator (22) consisting of a first double-sheathed optical fiber (6), an optical amplifier consisting of a second double-sheathed optical fiber (10), first (33) and second (35) optical coupling means capable of coupling said pump wave onto at least one of the two optical fibers (6) and (10). According to the invention, at least one of the two fibers has a configuration according to which the pump wave coupled to this optical fiber (6) or (10) is partially absorbed, generating a residual pump wave which is coupled to the other optical fiber (6) or (10) by second optical coupling means, and said second optical fiber (10) has a length greater than that of the first optical fiber (6).
