  • Publication number: 20080080570
    Abstract: A tunable pulsed laser source includes a seed source adapted to generate a seed signal and an optical circulator having a first port coupled to the seed source, a second port, and a third port. The tunable pulsed laser source also includes a modulator driver adapted to produce a shaped electrical waveform and an amplitude modulator coupled to the modulator driver and adapted to receive the shaped electrical waveform. The amplitude modulator is characterized by a first side coupled to the second port of the optical circulator and a second side. The tunable pulsed laser source further includes a first optical amplifier characterized by an input end and a reflective end. The input end is coupled to the second side of the amplitude modulator. Moreover, the tunable pulsed laser source includes a second optical amplifier coupled to the third port of the optical circulator.

  • Publication number: 20080030847
    Abstract: A method of operating a fiber amplifier characterized by a spectral gain curve includes providing an input signal at a signal wavelength. The signal wavelength lies within an in-band portion of the spectral gain curve extending from a first in-band wavelength to a second in-band wavelength, the in-band portion being characterized by a first amplitude range. The method also includes providing pump radiation at a pump wavelength. The pump wavelength is less than the signal wavelength. The method further includes coupling the pump radiation to the fiber amplifier and amplifying the input signal to generate an output signal. All portions of the spectral gain curve at wavelengths less than the first in-band wavelength and greater than the pump wavelength are characterized by a second amplitude less than or equal to 10 dB greater than the first amplitude range.

  • Publication number: 20070248138
    Abstract: A high power pulsed optical source includes a multi-port optical circulator and a seed source coupled to a first port of the multi-port optical circulator. The seed source is adapted to provide amplified spontaneous emission. The high power pulsed optical source also includes a first reflective device coupled to a second port of the multi-port optical circulator and a first double-pass optical amplifier coupled at a first end to a third port of the multi-port optical circulator and coupled at a second end to an amplitude modulator. The high power pulsed optical source also includes a second reflective device coupled to the amplitude modulator and an output port coupled to a fourth port of the multi-port optical circulator.
