Title
(EN) AN OPTICAL LIGHT SOURCE
(FR) SOURCE LUMINEUSE OPTIQUE
Abstract
(EN)
An optical light source comprising a laser diode (1), a beam shaping optics (2), and an amplifying fibre (3), wherein the amplifying fibre (3) comprises a waveguide (4) comprising a core (5) and a cladding (6), wherein the waveguide (4) is doped with a rare earth dopant (7), and wherein the laser diode (1) can produce optical pump power (8) which is coupled to the waveguide (4) by the beam shaping optics (2).
(FR)
L'invention concerne une source lumineuse optique qui comprend une diode laser (1), un dispositif optique de mise en forme du faisceau (2), et une fibre amplificatrice (3). La fibre amplificatrice (3) comprend un guide d'onde (4) comprenant un coeur (5) et une gaine (6), le guide d'onde (4) est dopé avec un dopant de terre rare (7), et la diode laser (1) peut produire une puissance de pompage otique (8) reliée au guide d'onde (4) par le dispositif optique de mise en forme du faisceau (2).
