Portable optical ablation system
View Patent ↗The present invention includes an apparatus and method of surgical ablative material removal “in-vivo” or from an outside surface with a short optical pulse that is amplified and compressed using either an optically-pumped-amplifier and air-path between gratings compressor combination or a SOA and chirped fiber compressor combination, wherein the generating, amplifying and compressing are done within a portable system.
1. A system comprising:
a pulse generator;
a man-portable amplifier and compressor combination to amplify the pulses and compress the pulses to generate amplified compressed pulses;
a handheld probe to apply the amplified compressed pulses to an object in order to remove material therefrom; and
an optical-fiber-containing umbilical cable to transport the pulses between components, the optical-fiber-containing umbilical cable including a feedback loop including a device to measure light leakage proportional to at least one of pulse power and energy to create a feedback loop.
2. The system of claim 1 , wherein the optical-fiber-containing umbilical cable transports the amplified compressed pulses from a compressor to a handheld probe.
3. The system of claim 1 , wherein the system removes surgical ablative material from a body with a short optical pulse that is amplified and then compressed.
4. The system of claim 1 , wherein the system generates an initial wavelength-swept-with-time pulse in a pulse generator.
5. The system of claim 4 , wherein the system amplifies the initial wavelength-swept-with-time pulse using an optical amplifier, to generate an amplified pulse.
6. The system of claim 1 , wherein the system generates a compressed optical pulse, wherein the amplification and compression are performed with either an optically-pumped-amplifier and air-path between gratings compressor combination, or a semiconductor optical amplifier and chirped fiber compressor combination.
7. The system of claim 6 , wherein the system applies the compressed optical pulse to a body, wherein the pulse generation, amplification, and compression are performed within a man-portable system.
8. The system of claim 7 , wherein the amplifier to amplify the initial wavelength-swept-with-time pulse includes more than one optical amplifier operated in a train mode to amplify the wavelength-swept-with-time pulse.
9. The system of claim 7 , wherein the compressor to compress the amplified pulse compresses pulses from more than one fiber-amplifier.
