Objective
The aim of this project is to apply a tuneable, 10 microns, short pulse, high power emission to study both the second harmonic generation (SHG) and third harmonic generation (THG) in different gases (SF6, CH4), new materials (nematic crystals, fullerens), polymers and semiconductors.
Under strong power infrared lighting, the weak non-linear emissions (transmitted or reflected by the materials) will be filtered and analysed, in the time and frequency domain, to derive the non-linear polarizability and relaxation time. Besides this, to extend this infrared non-linear spectroscopy in another frequency range, the 10 microns pumping sources will be converted in the 5 microns region, by means of efficient non-linear materials as proustite.
To attain this objective a tuneable 10 microns laser will be built, totally free from spurious non-linear signals and with a few-nanosecond pulse duration. In a further approach a CO2 amplified, picosecond ten microns pulse will be obtained by means of parametric conversion of a near infrared source, so that the dynamics of the non-linear effects can be analysed in the picosecond range. Alternatively, the ten microns sub-nanosecond pulse can be directly extracted from a high pressure CO2 oscillator by means of a neodymium laser. All these sources will be converted at 5 microns wavelength to perform the same non-linear spectroscopy in another frequency range.
