The rise in output power from rare-earth-doped fiber sources over the past decade, via the
use of cladding-pumped fiber architectures, has been dramatic, leading to a range of fiber …

Ultrafast fiber lasers have gained rapid advances in last decades for their intrinsic merits
such as potential of all-fiber format, excellent beam quality, superior power scalability, and …

Recent developments in nonlinear optics have led to the discovery of a new class of
ultrashort pulse, the 'optical similariton'. Optical similaritons arise when the interaction of …

We will ask and partly answer a few questions. What is the difference between a laser and a
light bulb? In which frequency ranges are lasers available? Which are the sizes and the …

Femtosecond laser micromachining has excited vivid attention in various industrial fields
and in medicine owing to the advantages of ultrashort laser pulses compared to long-pulse …

We propose a new method for generating a parabolic pulse by use of a dispersion-
decreasing fiber with normal group-velocity dispersion. When a hyperbolic dispersion …

The fiber laser, with its humble beginning in the late 1980s, has undergone tremendous
development in the past decade or so, transforming itself from a research curiosity to a major …

We report on highly efficient transmission gratings in fused silica with a grating period of 800
nm generated by electron-beam lithography. At a wavelength of 1060 nm, 95% diffraction …

Isotope shifts in the nuclear charge radius of even and odd calcium isotopes are calculated
within the nuclear shell model. The model space includes all configurations of nucleons in …

We report on the experimental demonstration of an all fiber CPA system based on a step-
index fiber stretcher and an air-guiding photonic crystal fiber compressor. The ultrafast fiber …
