摘要
PROBLEM TO BE SOLVED: To provide methods and constitutions for realizing a fiber, which is useful as a delivery fiber for ultrashort pulses for a wide variety of applications and is capable of propagating and compressing high energy femtosecond pulses, and an all-fiber optical pulse compression arrangement.;SOLUTION: The all-fiber optical pulse compression arrangement comprises a concatenated arrangement of a section of an input fiber (e.g. a single fiber), a graded-index (GRIN) fiber lens and a section of a pulse-compressing fiber (e.g. an LMA fiber). The GRIN fiber lens is used for providing mode matching between the input fiber (supporting the propagation of chirped optical pulses) and the pulse-compressing fiber so that efficient pulse compression occurs along the length of the LMA fiber. The dispersion and length of the LMA fiber section are selected to provide the desired degree of pulse compression, for example, so that a femtosecond pulse can be reconstituted as is used in supercontinuum generation systems.;COPYRIGHT: (C)2010,JPO&INPIT
