1. A device for generating tunable light pulses comprising:

  • (a) a pulse laser light source configured to produce femtosecond light pulses having an optical spectrum and a temporal frequency progression (“

    chirp”

    );

    (b) an adjustable optical compressor configured to change the chirp of the light pulses output from the pulse laser light source; and

    a non-linear optical fiber configured to modify the optical spectrum of the femtosecond light pulses and for tuning the generated light pulses coupled out of the non-linear optical fiber to the desired wavelength in accordance with the chirp of the light pulses received from the adjustable optical compressor.
