Ultrabroadband infrared fluorescence emission was demonstrated from a glass-clad Cr:forsterite crystal fiber. By combining the broadband fluorescence of Cr4+ and Cr3+ active ions in the Cr:forsterite fiber, the resultant spectrum exhibited a 3-dB bandwidth of more than 250 nm, a 10-dB bandwidth of more than 400 nm and a center wavelength in the near infrared region when pumped with a laser of visible wavelengths. Milliwatt-level continuous-wave fluorescence power was obtained at room temperature by using a 0.5W laser-diode pump. This new optical fiber material has potential applications in optical coherence tomography, tunable lasers, femtosecond lasers, optical communications and optical sensors.
