An all-fiber optical pulse compression arrangement comprises a concatenated arrangement of a section of input fiber (e.g., a single mode fiber), a graded-index (GRIN) fiber lens and a section of pulse-compressing fiber (e.g., LMA fiber). The GRIN fiber lens is used to provide mode matching between the...http://www.google.com/patents/US7957619?utm_source=gb-gplus-sharePatent US7957619 - All-fiber module for femtosecond pulse compression and supercontinuum generation
