Abstract
A pulsed fiber laser apparatus for outputting picosecond laser pulses can comprise a fiber delivered pulsed seed laser for providing picosecond optical seed pulses, and at least one optical fiber amplifier in optical communication with the fiber delivered pulsed seed laser. The optical fiber amplifier can comprise a gain optical fiber that receives and optically amplifies picosecond optical pulses by operating in a nonlinear regime wherein the picosecond optical pulses can be spectrally broadened by a factor of at least 8 during amplification thereof. The apparatus can further comprise a pulse compressor apparatus in optical communication with the optical fiber amplifier for providing compressed picosecond optical pulses. The pulse compressor apparatus can provide a dispersion of at least 50 ps/nm and can provide a compression ratio of the time duration of the picoseconds optical pulses received by the pulse compressor apparatus to the time duration of the compressed picosecond optical pulses of no greater than about 50.
