Abstract

A broadband Cr4+:YAG double-clad crystal fiber light source with a collimated output power of 3.15mW was demonstrated by using a bidirectional pump scheme. The bidirectional pump scheme increased the pumping efficiency and reduced the thermal problem along the fiber. Good agreement on the output power of the broadband fluorescence was achieved between experiment and theory, which showed a peak net gain coefficient of 0.03cm1 at the center wavelength near 1380nm. The 3dB bandwidth of 222nm with a Gaussian-like spectrum makes it eminently suitable for broadband interferometric technique to have low image cross talk. The calculated interference signal shows a 3dB width of 3.62μm with a cross talk smaller than 24dB for adjacent axial image pixels.
