Gain-switched laser diode seeded diode-pumped regenerative amplifier for microjoule picosecond tunable UV pulses

Summary form only given. Injection seeding of ultrashort semiconductor lasers into solid-state amplifiers is a simple way to reduce the size of femtosecond or picosecond high-energy laser systems. We present for the first time a very compact system combining a picosecond laser diode with a diode pumped regenerative amplifier capable of generating tunable microjoule UV pulses by frequency conversion. The system used an indirectly diode-pumped Ti:sapphire laser amplifier.
