The performance of a ruby laser amplifier is described and compared with a theoretical model. The ruby laser amplifier was driven by a Q-switched laser oscillator with a stable output, whose properties are due, in part, to a newly developed output coupler and a spinning roof-top prism for Q-spoiling.

Nd:MgO:LiNbO_3 waveguide laser and amplifier
Optics Letters, 1990Nd:MgO: LiNbO3 is a promising material that combines the good laser gain of Nd3+with the electro-optic and nonlinear properties of LiNbO3.1-3 In a waveguide configuration, this combination offers the possibility of realizing highly efficient laser-diode-pumped lasers and amplifiers, self-frequency doubled lasers, integrated laser/modulator structures ...

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 ...

Above-threshold laser amplifier
Physical Review Letters, 1991We have measured gain profiles by light-beating techniques for an argon-ion laser operated above threshold. The observed behavior is interpreted by developing a theory which incorporates four-wave mixing of signal and image frequencies. The gain shows the typical characteristics of a second-order phase transition.

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.

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.

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.
