The development of compact femtosecond lasers that are capable of being pumped by laser diodes or are based on laser diodes directly is described. Particular attention is paid to crystal-based femtosecond sources having high efficiencies and those operating at high repetition rates in the telecommunications window at around 1500nm. Work in progress on the design and development of mode-locked quantum-dot diode lasers that operate into a femtosecond regime is also described.
