Resumen
Depressed tubular cladding waveguides have been produced in
Nd:GGG crystals by using multiple inscription with femtosecond (fs) laser
pulses. The guiding cores are located inside the tubular regions with crosssection
diameters of 90-150 μm, which are surrounded by fs-laser induced
low-refractive-index tracks. At room temperature continuous wave (cw)
laser oscillations at wavelength of ~1063 nm have been realized through the
optical pump at 808 nm. The slope efficiency of the cladding waveguide
lasers is as high as 44.4% and the maximum output power at 1063 nm is 209
mW, which shows superior laser performance to the Type II stress induced
Nd:GGG waveguides.
