Abstract

High-brightness near-infrared broadband amplified spontaneous emission (ASE) was generated by glass-clad Ti:sapphire crystal fibers, which were developed using the co-drawing laser-heated pedestal growth method. As much as 29.2 mW of ASE power was generated using 520 nm laser diodes as the excitation source on an a-cut, 18 μm core-diameter Ti:sapphire crystal fiber (CF). The 3 dB bandwidth was 163.8 nm, and the radiance was $53.94\mathrm{W}·{\mathrm{mm}}^{-2}{\mathrm{sr}}^{-1}$. The propagation loss of the glass-clad sapphire CF measured using the cutback method was $0.017{\mathrm{cm}}^{-1}$ at 780 nm. For single-mode applications, more than 100 μW of power was coupled into a SM600 single-mode fiber.
