• Brief description of your expertise / expertise you are looking for:

  Our expertise is in surface characterization (by FTIR, AFM), chemical analysis (LIF, HPLC-MS) and nano-particles syntheses. Our team is looking to develop a new technique for surface characterization based on laser-mater interaction. We are looking forward to collaborate with partners experienced in Lasers, Ab initio calculations, NMR, EPR. Surface Plasmons, Spectroscopy, etc. Please do not hesitate to contact us.

• Brief description of your project / the project you would like to join:

  Magnetic resonance (MR) is a quantum mechanical resonant effect that can appear when a magnetic dipole is exposed to a static magnetic field and perturbed with another, oscillating electromagnetic field. MR is a recognized technique for its sensibility in molecular studies and also for its specificity. The classical way to make an MR setup is by sending RF pulses through a probe by means of a coil, all the system being in a magnetic field. The frequency of the RF is corroborated with the magnetic field and with the probe in order to excite hyper-fine transitions. The old method presumes that MR signal is collected via the same RF coil, new methods collects the MR signal by means of opto-mechanical systems. We propose a new system for creating RF pulses, in a MR setup, by means of a laser beam. The longitudinal modes of the laser will be adjusted to provide a beating mode in range MHz-GHz. The adjustment of the longitudinal modes will be done by adjusting the laser cavity length. The laser can function in CW but also pulsed in Q-switch or Mode-locked mode in order to obtain a high instant power. Gold nano-particles, introduced in samples by spray or other methods, will develop high electric fields on the surface, electric fields also with a frequency equal to the beating mode frequency of the laser. The beating mode frequency could vary in a range from 0.1 GHz-100 GHZ covering the spectra for NMR and EPR spectroscopy at ordinary magnetic fields.
