摘要： Laser-based methods and systems for selectively processing or damaging biological target material characterized by an absorptive coefficient in a therapeutic procedure are provided. The lasers typically are fiber lasers. Also, methods and systems which use spectroscopy are provided to selectively diagnose the presence of certain tissue types. One of the methods includes generating an output laser beam along a propagation path. The beam has optical and temporal properties and a predetermined wavelength based on the absorptive coefficient of the target material. The path extends through an opening in a body and into an interior body cavity. The method further includes delivering and focusing the output laser beam into a plurality of spots on the target material for a duration sufficient to allow laser energy to be absorbed by the target material and converted to heat to produce a desired physical change in the target material without causing undesirable changes to adjacent non-target material having an absorptive coefficient different than the target material at the predetermined wavelength.

摘要： A method and system for self-synchronizing an optical packet network by selecting a seed pulse from among the data pulses within a packet having no synchronization marker, transforming the seed pulse to be optically distinguishable from the remaining data pulses after the packet has been transmitted, and extracting that seed pulse (20) for use in synchronizing the operation of the network. In one embodiment, the process is practiced using a intensity modifier (26) (such as a fast-saturation, slow-recovery amplifier) to modify the seed pulse intensity, and an intensity discriminator (32) (such as an unbalanced NOLM, or a dispersion-shifted fiber and bandpass filter) to extract the differentiated seed pulse.

In one particular embodiment, the pump signal wavelength resides in the anomalous group- velocity dispersion regime of the first fiber and where different intensities in the pump signal can cause relative motion between different parts of the modulated pump signal produced through modulational instability in the first fiber. The light source also including a nonlinear element that is coupled to the first fiber that is capable of broadening the pump optical spectral width to at least 100nm through a nonlinear effect in the nonlinear element.

摘要： A supercontinuum light source includes a modulated pump laser, a first fiber, and a nonlinear waveguide. The modulated pump laser generates light comprising longer pulses, where a longer pulse has a temporal duration of approximately ten picoseconds or more. The first fiber breaks at least one longer pulse into shorter pulses, where a shorter pulse has a temporal duration of approximately two picoseconds or less. The first fiber at least partially operates in an anomalous group velocity dispersion regime, and the shorter pulses result from a modulational instability in the first fiber. The nonlinear waveguide spectrally broadens the shorter pulses to yield supercontinuum light, where the supercontinuum light has a spectral width of approximately 150 nanometers or more.
