Erbium-doped fiber amplifiers are modeled using the propagation and rate equations of a
homogeneous two-level laser medium. Numerical methods are used to analyze the effects …

Rare-Earth-Doped Fiber Lasers and Amplifiers, Second Edition discusses the essential
principles, operating characteristics, and current technology of the main fiber laser and …

We report on the realization of a whispering-gallery-mode laser based on neodymium-
doped silica microspheres. Absorbed pump powers at threshold are as low as 200 nW. The …

Perylene-terminated monodendrons 1− 7 and phenyl-terminated reference monodendrons
8− 14 have been synthesized, and the intramolecular energy transfer has been studied …

Since quantum information technologies are expected to offer communication security and
high computational capacities, research in the field is currently attracting a lot of attention …

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 …

Amplification of spontaneous emission (ASE) in erbium-doped single-mode fiber amplifiers
operating at lambda= 1.53 mu m is studied theoretically and experimentally. The ASE noise …

This review describes our study on preparation of alumina films by a sol-gel process and
their several applications that have been investigated since 1986. Alumina films were …

I offer some reflections on the past three decades of high-resolution spectroscopy of rare-
earth ions in solids which was ushered in by the development of tunable lasers in the mid …

Gain compression effects during multichannel signal amplification in an erbium-doped fiber
amplifier at lambda= 1.53 are investigated. A theory is presented that accurately models the …
