  • Method and system to simultaneously generate tunable redshift and blueshift femtosecond laser pulses with adjustable spectral bandwidth and output power
    Patent number: 11876335
    Abstract: A method and a system are provided to simultaneously generate blue-shifted and red-shifted femtosecond light sources with tunable spectral peak location and bandwidth, by controlling the input condition (chirp/spectrum) of a fiber-optic nonlinear propagation. The system comprises (A) a seed source, (B) a driving current controller to regulate the spectrum of the seed source, (C) a dispersion controller to control the chirp and pulse width of the seed source, (D) a fiber-optic spectral conversion module to shape and broaden the laser spectrum via fiber-optic nonlinear processes, and (E) a spectral selection module to filter out the required wave packets. With the simultaneous uses of the driving current controller and the dispersion controller, the light sources feature continuously tunable spectral peak with (1) a relatively constant output pulse energy or (2) a tunable spectral bandwidth at a specific peak location.
