Abstract

Spectrally resolved interferometry combining up-chirped and down-chirped pulses allows for millimeter range resolution in laser ranging applications. Key in our approach is the use of temporally stretched optical pulses of 5 nanoseconds in duration. These stretched pulses were obtained from a femtosecond semiconductor mode-locked laser and were up-chirped and down-chirped using a chirped fiber Bragg grating and recombined to realize spectral interferometry. This approach provides a means to achieve the high pulse energies required for a laser radar application which are easy to achieve using nanosecond pulses but maintains the high spatial resolution associated with femtosecond optical pulses.
