Laser-amplifier gain and noise
Physical Review A, 1993A theoretical study is presented of the gain and the noise spectra of laser amplifiers at pumping rates both above and below the oscillation threshold. The theory is valid for both class- A and class-B laser systems, where the decay rate of the collective atomic dipole moment greatly exceeds the decay rates of the atomic population inversion and the ...

Ultrafast disk lasers and amplifiers
SPIE Proceedings, 2012Disk lasers with multi-kW continuous wave (CW) output power are widely used in manufacturing, primarily for cutting and welding applications, notably in the automotive industry. The ytterbium disk technology combines high power (average and/or peak power), excellent beam quality, high efficiency, and high reliability with low investment and operating

Amplified spontaneous emission (ASE) in laser oscillators and amplifiers
IEEE Journal of Quantum Electronics, 1983Dye-laser oscillators and amplifiers are studied theoretically with inclusion of amplified spontaneous emission (ASE). Assuming pencil-like geometry in both cases, laser signal intensity and ASE intensity are described with appropriate photon-transport equations.

Amplified Extended Modes in Random Lasers
Physical Review Letters, 2004We report on a new random laser phenomenon that gives rise to narrow emission modes without requiring optical cavities. Sharp emission peaks are observed experimentally over a broad range of scattering strengths and analyzed in numerical calculations.

Frequency conversion in semiconductor lasers and amplifiers
European Transactions on Telecommunications, 1994AbstractDifferent methods to obtain frequency conversion in optical systems using nonlinear effects in semiconductor devices are analyzed and discussed. In particular, some recent results obtained on the frequency conversion by gain saturation and four wave mixing (FWM) in semiconductor lasers and amplifiers are reported.

Recent performance of alexandrite single- and double-pass amplifiers is described. Amplification factors of 5x per pass are reported at pulse energies of several joules/pulse and pulse powers exceeding 100 MW.

A laser-amplifying device is proposed which is based on the stimulated decay of excitons in a pure crystal. An estimate is made of the gain of the device. At a typical frequency the gain is found to be appreciably large, thus suggesting practical application of the laser amplifier.

Dielectric Waveguide Amplifiers and Lasers.
2014The performance of semiconductor amplifiers and lasers has made them the preferred choice for optical gain on a micro-chip. In the past few years, we have demonstrated that also rare-earth-ion-doped dielectric waveguides show remarkable performance, ranging from a small-signal gain per unit length of 1000 dB/cm, via integrated distributed-feedback ...
