Abstract (en)
[origin: WO9415385A1] Laser device of a lengthened and monolithic structure to be used in telecommunications of the type including a pumping laser (1) suitable to emit a radiation at a wavelength lambda 1, a resonating cavity (2) and an optical fibre rod (6). The resonating cavity comprises a first and second mirror (4 and 5) and a portion of active material (3) suitable to emit a radiation at the wavelength lambda 2 > lambda 1. The first mirror (4) is set up on the surface of the portion of active material (3) facing the pumping laser (1), and is highly transparent at the radiation lambda 1 and highly reflecting at the radiation lambda 2. The second mirror (5) is set up on the surface of the portion of active material (3) facing the optical fibre rod (6) and highly reflecting at the radiation lambda 2.
