Abstract
Official abstract text for this publication.
Embodiments of the present invention describe systems and methods for delivering ultrashort laser pulses through an optical fiber system with higher order mode fiber output and without pre-chirping. In one embodiment of the present invention, an all-fiber delivery system comprises a mode-locked solid-state or fiber laser for generating laser pulses in the 0.2 μm to 1.3 μm wavelength range, a single mode fiber with normal dispersion, and a long-period-grating mode converter, and a higher order mode fiber with anomalous dispersion, wherein the all-fiber delivery system is free of bulk optics, and propagates laser pulses without pulse pre-chirping, and wherein higher order mode output beam from the all-fiber delivery system comprises pulses at less than about 200 femtoseconds.
First claim
Opening claim text (preview).
What is claimed is: 1. An all-fiber delivery system for femtosecond laser pulses without pulse pre-chirping comprising: a first fiber with normal dispersion; and a higher order mode fiber with anomalous dispersion, the higher order mode fiber having a relative dispersion slope substantially equal to that of the first fiber and having an effective area of about 14.9 μm 2 ; wherein the all-fiber delivery system is free of bulk optics and is suitable for producing a resulting hig…
