The spectral distributions of 8-psec ultrashort laser pulses propagating through multimode
glass fibers were measured and compared with those of single-mode fibers at comparable …

We demonstrate experimentally and theoretically that frequency-modulated femtosecond
laser pulses can be spectrally narrowed by self-phase modulation in optical fibers. We …

The compression of frequency swept (in time) or" chirped" optical pulses was independently
proposed by Gires and Tournois (1964) and Giordmaine et al.(1968). Optical pulse …

The experimental self-phase-modulation spectra of 55-fsec optical pulses after propagation
along 11 mm of monomode fiber are compared with the computed spectra obtained by a …

We present theoretical calculations and experimental measurements of self-phase-
modulation spectra generated with picosecond laser pulses at 532 and 1064 nm …

The spectra of picosecond pulses with peak powers of up to 1 kW transmitted through a 12
m singlemode fiber have been investigated. Asymmetric broadening and the creation of an …

We describe the use of a mode-locked color-center laser to demonstrate nearly
distortionless propagation of~ 5-psec-wide, Fourier-transform-limited pulses, at or near the …

We report a strong spectral broadening of femtosecond pulses propagating in a single-mode
As-S glass fiber of 1.5 m length. The pump pulse spectrum is broadened by a factor of five …

Picosecond pulse dispersion measurements have been made on short lengths of multimode
glass fibre. With a narrow input beam rapid mode conversion occurs initially, but an …

Single-mode excitation of step-index multimode fibers with light sources with short temporal
coherence lengths is demonstrated. Multimode fiber designs with reduced microbending …
