We generate 136-fs pulses from a passively mode-locked diode-pumped ytterbium(Yb):yttrium aluminum garnet(YAG) laser. This is to our knowledge the shortest pulse from a Yb:YAG laser. We shift the laser center wavelength from the commonly used 1030 nm to around 1050 nm to utilize the Yb:YAG spectrum broader.
