Abstract: In one aspect, a method includes forming range bins from range compressed data, the range compressed data comprising a train of coherent pulses formed based on a transmitted signal from a laser detection and ranging (LADAR) sensor and having a large time-bandwidth product and for each range bin, compensating for motion of the LADAR sensor, performing a Fourier transform on the compressed range data, determining a centroid of individual velocity measurements and performing Fourier transform of the centroid to determine a vibration.

Abstract: According to an embodiment of the disclosure, a laser system (100,200) comprises a pump diode (104,204), fiber (110,210), relay optics (120,220), and a microchip laser crystal (130,230). The pump diode (104,204) is configured to produce light at a first wavelength. The fiber (110,210), coupled to the pump diode, is configured to receive the light from the pump diode and to produce a round, homogeneous light spot at an output of the fiber. The relay optics (120,220) are configured to receive the light from the fiber. The microchip laser crystal (130,230) is configured to receive the light from the relay optics and to produce a linearly polarized single frequency output (140,240) at a second wavelength. The microchip laser crystal includes a first layer (132,232) and a second layer (136,236). The first layer (132,232) is configured to absorb the light at the first wavelength and emit light at the second wavelength. The second layer (136,236) is configured to receive the light at the second wavelength and to either provide a polarization dependent loss at the second wavelength or maintain a polarization of the light at the second wavelength.

Abstract: In accordance with various aspects of the disclosure, a method, an apparatus and a system for characterizing and compensating for deterministic phase nonlinearities and distortion inherent in radio frequency and optical components utilized to synthesize a single sideband suppressed carrier optical waveform in the presence of random phase noise generated by an optical carrier source is disclosed. The method comprises mixing a modulated optical signal with a continuous wave optical signal in an optical coupler; optically heterodyning the mixed signal output from the optical coupler in a detector to produce a radio frequency waveform; and analyzing the produced radio frequency waveform in a processor based on a phase history of a preselected continuous wave signal to measure distortion characteristics of the radio frequency modulated optical signal.
