Optical pointing and tracking system

A system comprising:

• a probe laser device configured to transmit a probe pulse towards an object, thereby obtaining, after reflection of the probe pulse from a reflection area of the object, a reflected probe pulse,
• an optical subsystem comprising a reorientation module, wherein the reorientation module comprises a film polarizer, a medium, a phase conjugate mirror, wherein a path of the reflected probe pulse from its reflection by the object up to the film polarizer of the reorientation module is designated as a reflected probe path,
• a pump laser device configured to transmit at least one sequence of pump laser pulses, wherein the pump laser pulses have a wavelength which match a wavelength of the probe pulse according to a matching criterion,
• wherein the reorientation module is operative to:
• use the phase conjugate mirror to generate a phase conjugated reflected probe pulse, which is phase conjugated with the reflected probe pulse,
• receive, by the medium:
• the phase conjugated reflected probe pulse, and
• sequentially, a plurality of pump laser pulses of the sequence of pump laser pulses, thereby generating, in the medium, a grating,
• reflect, using the grating in the medium, the plurality of pump laser pulses as a plurality of reoriented pump laser pulses, wherein each given reoriented pump laser pulse of the plurality of reoriented pump laser pulses exits the film polarizer of the reorientation module along a path coinciding with the reflected probe path, to illuminate the object.
