Abstract

Laser device to be used as a continuous wave source of a single-mode and monochromatic radiation in telecommunications of the type including a pump laser (1) suitable to emit a radiation with a wavelength of μ1, a resonating cavity (2) and an optical fibre rod (8). The resonating cavity includes at least a first and second mirror (6 and 7), and at least a portion of active material (3, 4; 30) suitable to emit a radiation with a wavelength of μ2. The first mirror (6) is highly transparent to the radiation μ1 and highly reflecting the radiation μ2, and the second mirror (7) is highly reflecting the radiation μ2.
