Assembly “Ultrasonic laser for surface wave generation (100 kHz_100 MHz)” with interferometric detection (1 Quantel 20Hz Picosecond laser + 1 Helium_Neon).   Surface wave generation is obtained by illuminating the sample surface with a...

Generation and detection of surface acoustic waves via interdigital transducers Surface acoustic waves are excited by interdigital combs (IDT) lithographed on the sample. IDTs are usually excited by wave trains provided by a sinusoidal...

  Thermo-reflectance Microscopy Assembly   Modulated ThermoReflectance is a non-contact method that allows to follow the heat diffusion in modulated regime induced in a sample and consequently to deduce its thermal properties thanks to...

Asynchronous Optical Sampling (Real Time Stroboscopy) ASOPS   Since 2010, a new concept of pump-probe measurement has been studied and implemented on our experimental benches: Asynchronous Optical Sampling (ASOPS), which consists in using 2...

  Material: 3 femtosecond lasers 80 MHz SpectraPhysics 2 cavities Tsunami 3W and 1W, 1 cavity Mai_Tai 2W, 1 OPO (Optical Parmetric Oscillator 500nm-1.6µm), 1 pulse picker doubler, 1 furnace for temperature study of...

  Polarized light interferometric assembly for quantitative mapping of surface waves   This assembly was developed as part of a study on the Non-contact handling of fluids and particles using acoustic fields. Surface acoustic...

  Experimental set-up acoustic clamps The experimental set-up described below was developed in the framework of a thesis on manipulation and trapping by acoustic radiation pressure. This type of trap based on the use...

Team Permanent Member: Daniel Garcia Sanchez Chercheur invité : Bernard Perrin Quantum optomechanics and electromechanics is a fast growing field with promising applications in quantum information. Recently non-classical mechanical states have been realized. However,...

  Equipe Permanent Member: Jean-Louis Thomas Non-contact handling of solid objects is possible by using the forces exerted by electromagnetic or acoustic fields [1,2]. Optical tweezers are the best known example and earned A....

Team Permanent member: Olga Boyko Emeritus researcher: Bernard Bonello   Theorical aspects Following the example of what happened about twenty years ago for photonic crystals, we are currently witnessing a certain effervescence around phononic...
