SiO
₅
(Yb: SSO) are investigated. The laser produced a maximum cw output of 2.73 W at 1063 nm. The corresponding slope efficiency and optical to optical efficiency were 70 % and 59 % respectively. The laser mode-locked at 1041 nm, 1060 nm and 1077 nm with near Fourier transformed limited pulse width of 145 fs, 144 fs and 125 fs with average output power of 40 mW, 52 mW and 102 mW, respectively.
