Introduction to physics and to laser and fiber optics technologies in connection with their applications in the biomedical field.

Physics and technology of lasers: - The foundations of the laser cavity: optical properties, resonance, the cavity losses and amplification. - Continuous or pulsed lasers, particularly bundles or not- bundles used in the biomedical community.

Introduction to Fiber Optics: -Guidage of Light (Concept of total reflection, numerical aperture, modes, cutoff frequency, propagation constants, dispersion). Optical -Fibres: single mode / multimode, materials, fabrication, photonic crystals. -Capteurs Optical fibers: measurement chain, components, Bragg grating fiber.
