✦ Synopsis

A diode-pumped picosecond laser was demonstrated with Yb 3+ -doped yttrium lanthanum oxide transparent laser ceramic Yb:(Y 1-x La x ) 2 O 3 (x = 0.1), which was fabricated with nanopowders and sintered in H 2 atmosphere. Passive modelocking was realized for the first time to our knowledge with a semiconductor saturable absorber mirror, generating pulses of 174 ps at the central wavelength 1032.5 nm with the average output power 162 mW under a diode-laser pump power of 3.2 W. Intensity, arb. units Time, 20 ns/div The 90.7-MHz repetition rate of the CW mode-locked Yb:Y 1.8La0.2O3 ceramic laser pulses
