New developments on Q-switched and mode-locked solid state lasers are reviewed.
Both pulsed and continuous working systems are considered. Nd:YAG, Nd:glass, and
ruby are still the most widely used pulsed short pulse solid state laser materials.
Cw mode-locked and Q-switched Nd:YLF lasers gain importance as pump sources of pi-
cosecond and femtosecond dye lasers. Short pulse tunable alexandrite and Ti:sapphire
lasers compete with near infrared dye lasers and find application in the amplification
of ultrashort dye laser pulses. Frequency tunable femtosecond pulses have been
generated in color center lasers. Diode laser pumping opens the way to all-solid-
state short pulse lasers. The coupled-cavity mode-locking technique (additive pulse
mode-locking), the seeding pulse amplification, and the regenerative chirped pulse
amplification are described.
