Abstract
There is proposed an optical fiber laser device which can also precisely perform a frequency control or the like in relation to a vertical mode of a resonator. A long piece of laser fiber 2a which has been wound multiple times is embedded with clearance and fixed in a transparent ultraviolet hardening resin 1a formed in a rectangular parallelepiped. Both end portions of the laser fiber are exposed to the outside. The laser fiber 2a is provided with a clad 6a on a periphery of a core 5a. Inside the core 5a, 0.5 at % of Nd.sup.3+ ion is doped.
