Abstract
A laser radar (LADAR) system includes a laser transmitter configured to emit laser pulses at a first wavelength, a non-linear converter configured to convert the laser pulses to a second wavelength prior to spectral filtering of amplified spontaneous emission (ASE) that is emitted from the laser transmitter in a spectrum concentrated around the first wavelength, and a spectral filter configured to substantially filter the ASE and allow the laser pulses at the second wavelength to pass.
