Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
We study the optical properties of strongly photo-excited GaAs/AlxGa1-xAs Quantum Wells in the one-dimensional optical amplifier geometry. One part of our work deals with gain measurements using the "variable stripe length method". We are proposing two new ...
We investigate, experimentally and theoretically, the optical amplification and its saturation in a mirrorless semicondctor quantum well laser. We optically excite a narrow stripe of variable length and measure the profiles of spontaneous and stimulated lu ...
Pump and Probe measurements with femtosecond pulses are performed on a Gain-Clamped Semiconductor Optical Amplifier (a special laser structure). The relaxation oscillations of the carriers density are observed directly in the time domain, Reasonable values ...
A general method is described for selecting and optimizing a gas mixt. which isolates the amplifier stages of a CO2 laser chain. The isolation increases the useful energy extd. by eliminating self-oscillation. The performance of an optimized nonsatg. gas m ...
