A novel method for making a compact high-power single-mode photonic crystal fiber laser (PCFL) is proposed. The entire photonic crystal fiber is doped uniformly with active material yet only the core is pumped. Numerical simulations predict that, by using Er-Yb codoped phosphate glass, it is possible to extract 9.5 W from a 1.8-cm-long PCFL with a 100-μm core diameter pumped with 20 W, achieving near 50% efficiency.
