Abstract: Ultrashort pulsed laser systems are described. In one example, a pulsed laser system includes a source laser configured to emit a pulsed source laser beam, a splitter configured to split the source laser beam into first and second input laser beams, a first amplifier module configured to amplify the first input laser beam using chirped pulse amplification (CPA) and to produce, at a first output port, a first output laser beam in a first spectral range based on soliton self-frequency shift (SSFS) in the first amplifier module, a second amplifier module configured to amplify the second input laser beam using CPA and to produce an intermediate beam based on SSFS in the second amplifier module, and a mid-infrared fiber configured to receive the intermediate beam and to produce, at a second output port, a second output laser beam in a second spectral range based SSFS in the mid-infrared fiber.
