Abstract:
A laser device comprising an excitation beam guide portion (2) for confining and propagating an excitation beam, and a longitudinal flexible laser beam guide portion (1) containing a laser active material for producing a laser beam (52) in response to the excitation beam (51) introduced from said excitation beam guide portion into said laser beam guide portion in a distributed state, said excitation beam guide portion being formed by winding or rounding a flexible beam guide member (21) into a predetermined shape to form a thin integral body as a beam guide structure, at least one long-sized laser beam guide portion as a single-series wave guide structure being wound or rounded around said excitation beam guide portion to be brought into optical contact therewith over an optical contact zone having a predetermined length so that the excitation beam is introduced from said excitation beam guide portion into said laser beam guide portion in the distributed state in which the excitation beam is distributed over said contact zone.
