Ultrashort pulse laser source with chirped pulse amplification and tailored pulse train

A fiber-based laser system comprising:

• a mode-locked laser source configured to provide an input train of input pulses having an initial pulse duration of less than one nanosecond and a pulse repetition rate of at least one MHz;
• an optical pulse stretcher optically coupled to the mode-locked laser source and configured to stretch pulse durations of the input train of input pulses to produce a train of stretched laser pulses;
• a pulse replicator module optically coupled to the optical pulse stretcher and configured to increase a pulse repetition rate of the train of stretched laser pulses to produce a modified pulse train of laser light;
• a fiber power amplifier optically coupled to the pulse replicator module and configured to amplify the modified pulse train to produce amplified laser pulses, the amplified laser pulses having a peak-average-power ratio of less than 30;
• and
• a pulse compressor optically coupled to the fiber power amplifier and configured to temporally compress the amplified laser pulses to produce amplified and compressed laser pulses.
