Abstract
Here we study the use of tunable three-section distributed-Bragg-reflector (DBR) diode lasers as pulse sources for chirped pulse amplification (CPA) in a fiber amplifier. The broad continuous-tuning range of the laser allows the generation of nanosecond linearly chirped pulses, which are amplified in a fiber amplifier up to microjoule energies and then compressed to transform-limited subpicosecond duration. The energy of these ultrashort pulses is more than two orders of magnitude higher than any previously reported energies from a compact diode laser and fiber source.
