Provided are systems and methods for long-range, high-resolution, laser radar range detection. In one embodiment such a system includes an optical pulse modifier configured generated a stretched optical pulse and an optical amplifier configured to increase an optical power of the stretched optical pulse The system can further include an optical spectrum analyzer configured to determine a wavelength of a spectral peak that results from interference between a first amplified stretched pulse that is reflected from a target and a second amplified stretched pulse that is spectrally reversed.
