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.
Frequency stabilization is generally performed by using atomic or molecular absorption lines. However, it is sometimes necessary to lock a laser at a frequency located outside of any absorption peaks. In this case, an offset locking configuration is necess ...
An electrically tuned nematic liquid crystal (LC) infiltrated photonic crystal (PC) laser was analyzed. LC tuning of the PC laser was demonstrated by recording the lasing wavelength as a function of the voltage applied across the LC cell. The PC laser betw ...
PURPOSE: Examination of morphology in corneal ablation induced by a q-switched Er:YSGG (2.79 mu m) laser and a free-running Er:YAG laser (2.94 mu m). ...
In this paper, we present a novel Brillouin fiber-ring laser utilizing an unbalanced Mach-Zehnder interferometer (UMZI) as coupling device. The laser is pumped by a distributed-feedback laser diode and shows continuous-wave and single-frequency operation. ...
The common configuration for deflecting laser beams in two dimensions is based on two single-axis galvanometric scanners placed perpendicular to each other. Over recent years, these fast scanners have proved to be both very reliable and very accurate. They ...
We examine the primary challenges for building a practical and competitive holographic random access memory (HRAM) system, specifically for size, speed, and cost. We show that a fast HRAM system can be implemented with a compact architecture by incorporati ...

For future divertor studies on TCV measurements of electron temperature and density and their spatial gradients along open flux surfaces will be of major interest. A Thomson scattering system is proposed for this purpose, which takes advantage of the good ...
Fabrication and characterization of a current-injected InGaAs-GaAs quantum-wire gain-coupled distributed feedback (DFB) laser operating at 77 K at a wavelength of 923 nm are presented, Threshold current densities in broad area lasers were measured to be as ...
We present a monolithically integrated coupled cavity vertical cavity surface emitting laser or BiVCSEL: this two-terminal electrically injected device exhibits stable laser emission at two design wavelengths simultaneously. The coupling between the two mo ...
Disclosed is a semiconductor laser that is constituted by at least one active layer sandwiched between two confinement layers with P and N type doping to constitute a PN junction. In at least one of the confinement layers and/or the active layer, holes are ...
