We describe an all solid-state (holosteric) laser source which produces subpicosecond pulses at 1.4 {mu}m. The system consists of a diode laser pumped Nd:YAG laser which is frequency modulated (FM) mode locked and {ital Q} switched at 1.32 {mu}m. In continuous wave operation the laser produces pulses of 19 ps while simultaneous {ital Q} switching and mode locking result in 30 ps pulses being contained in a {ital Q}-switched envelope of energy 2.1 {mu}J. The output of the laser, when passed through a 1 km single-mode optical fiber, produces a spectrally broad Raman signal with its peak at 1.4 {mu}m and the overall conversion efficiency at 12%. The pulse duration at 1.4 {mu}m has been measured to be 280 fs. We believe this is the first time that subpicosecond light pulses have been generated by an all solid-state laser system.
