Endoscope, microscope or endomicroscope for two-photon excitation of tissue

摘要

An endoscope, microscope or endomicroscope includes and optic fiber (20) for transmitting a pulsed main beam (14) along an optical path between a femtosecond laser (12) and the tissue sample (44). Reverse chirped Bragg grating fibers (28, 30) act to reverse the dispersion occurring in the optic fiber. An Independent claim is also included for the following: A method of two-photon endoscopy or microscopy using the principles of the described endoscope/microscope.
