Abstract

Experimental demonstration of an efficient energy extraction from heavily Er:Yb codoped phosphate-glass fiber is reported. In our experiments, sub- 20-ns pulses at 1.5 μm wavelength produced by an actively Q -switched all-fiber oscillator are amplified in 15 cm long, side-pumped phosphate fiber doped with 1 wt % of Er2 O3 and 8 wt % of Yb2 O3. Two types of active fiber are used, with core diameters of 14 and 25 μm. The pulse energy achieved with these fibers is 105 and 215 μJ, respectively, with nearly diffraction-limited beam quality. These experiments indicate a potential for further energy scaling beyond the millijoule level by increasing the core size of the fiber.
