Item Description: This article reports on a stable single-mode ion-exchanged ultra-compact high gain Er-Yb-doped waveguide laser providing high output power of over 20 mW at 1533.5 nm under single-end diode pumping. By exploiting the same fabrication technique we have demonstrated a high power multi-mode waveguide laser providing more than 160 mW output power and 46% slope efficiency, which represents to our knowledge the best power performance so far reported by Er-Yb-doped ion exchanged waveguide lasers. This suggests that ion-exchange technique is a promising solution to achieve 100-mW output power in single-mode operation by exploiting the high erbium solubility in phosphate glass substrates.
