Abstract:
1. A method for providing a plurality of signal pulses, the method comprising: providing a stabilizing optical radiation signal characterized by a first center wavelength, a first spectral linewidth, and an ooutput power; coupling the optical radiation signal into a first port of an optical combiner; transmitting the optical radiation signal from the first port to a second port of the optical combiner; coupling the optical radiation signal from the second port into a tunable pulsed laser source comprising a semiconductor laser; driving the tunable pulsed laser with drive signal to produce a plurality of signal pulses having temporal pulse shape, and including applying the drive signal to the semiconductor laser to adjust the temporal pulse shape in real time from pulse to pulse; injection locking the laser to stabilize the spectral linewidth of the plurality of signal pulses; coupling the plurality of signal pulses into the second port; transmitting the plurality of signal pulses from the second port to a third port of the optical combiner; and outputting the plurality of signal pulses from the third port; coupling the plurality of signal pulses into an input end of an optical amplifier; amplifying the plurality of signal pulses; and outputting the plurality of amplified signal pulses at an output end of the optical amplifier.
