A dual-wavelength laser at 1423 and 1406?nm is achieved with output power of about 2.59?W at absorbed pump power of 13.4?W. Further increasing the pump power, simultaneous tri-wavelength laser at 1423, 1415 and 1406?nm is also obtained with a maximum output power of 3.96?W at absorbed pump power of 18.9?W. Single-wavelength lasing is also
