We present a laser-diode-pumped passively mode-locked femtosecond disordered crystal laser by using Nd:CaGdAIO_4(Nd:CGA) as the gain medium.With a pair of SF6 prisms to control the dispersion compensation,laser pulses as siort as 850 fs at 1079 nm are obtained with a repetition rate of 124.6MHz.The measured threshold pump power is 1.45 W.A maximum average output power of 122 mW is obtained under the pump power of 5.9 W.These results show that Nd:CGA could be a promising laser medium for generating femtosecond ultrashort pulse at about 1 μm.
