Diode-pumped continuous-wave green upconversion lasing of Er(3+):LiLuF(4) using multipass pumping.
Powerful green upconversion lasing of Er(3+):LiLuF(4) was achieved with a multipass pumping setup. The maximum output was 213 mW for Ti:sapphire laser pumping. Diode-pumped cw lasing at room temperature is demonstrated for the first time to the authors' knowledge.
