Resumen
We report on the fabrication of depressed double-cladding
waveguides in Yb:YAG ceramics by using femtosecond (fs) laser
inscription. The double-cladding structures consist of tubular central
structures with 30 μm diameter and concentric larger size tubular claddings
with diameters of 100-200 μm. Continuous wave laser oscillations at
wavelength of 1030 nm have been realized at room temperature through
optical pump at 946 nm. The obtained maximum output power of the
double-cladding waveguide lasers is ~80.2 mW with a slope efficiency as
high as 62.9%.
