ResumoA diode-pumped picosecond laser was demonstrated with Yb3+-doped yttrium lanthanum oxide transparent laser ceramic Yb:(Y1-xLax)2O3 (x = 0.1), which was fabricated with nanopowders and sintered in H2 atmosphere. Passive mode-locking 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.
