LONG-PULSE-WIDTH VARIABLE-WAVELENGTH CHIRPED PULSE GENERATOR AND METHOD

摘要

A device for creating an optic pulse with different wavelengths separated by time. A pump laser is configured to output energy to a dye cell which, responsive to the energy, outputs an optic pulse. Mirrors direct the optic pulse away from the dye cell towards a spectrograph. The spectrograph has an input and two or more outputs. The spectrograph receives and converts the optic pulse to a wavelength separated optic signal presented on the two or more outputs. A first optic cable has an input end and an output end. The input end receives a first output from the spectrograph. A second optic cable has an input end and an output end. The input end receives a second output from the spectrograph. The second optic cable is a different length than the first optic cable to establish a time shift between the signals exiting the first and second cable.

1. A device for creating an optic pulse with different wavelengths separated by time comprising:
a pump laser configured to output energy; a dye cell configured to receive the energy from the pump laser and output a optic pulse; one or more mirrors configured to direct the optic pulse away from the dye container; a spectrograph having an input and two or more outputs, the spectrograph configured to receive the optic pulse on the input and convert the optic pulse to a wavelength separated optic signal that are presented on the two or more outputs; a first optic cable having an input end and an output end, the input end configured to receive a first output from the spectrograph; and a second optic cable having an input end and an output end, the input end configured to receive a second output from the spectrograph, the second optic cable having a different length than the first optic cable.
