<p><span lang="EN-GB">In this Lab we perform studies on the elastic and optical properties of different kinds of materials through the analysis of their scattered light (Brillouin Spectroscopy&nbsp;</span><span lang="EN-GB"><a href="#" onclick="show('40')">&ndash;&gt;&gt;BS</a></span><span lang="EN-GB">).&nbsp;<em><strong>The frequency shift of the scattered light is proportional to the propagation velocity of an acoustic wave in the material.</strong></em></span></p>

<p>&nbsp;<span lang="EN-GB">We study transparent and opaque materials both in bulk or film shaped.</span></p>
<p><span lang="EN-GB">In the first case we focus our studies on the evolution of the elastic and optical properties with temperature and pressure which are connected to structural changes.</span></p>
<p><span lang="EN-GB">In the second case our research activities are centred on Surface Acoustic Waves (SAW) and their relationship with the structure of the material.

<p><span lang="EN-GB">For the&nbsp;<em><strong>MicroBrillouin</strong></em>&nbsp;technique we use an&nbsp;<strong>Olympus BX51</strong>&nbsp;microscope with 10X, 20X and 50X objectives.</span></p>

In this way we are able to perform measurements between room temperature and 5K.</span></p>
<p><span lang="EN-GB">High temperatures, up to 500&ordm;C, are obtained with a &ldquo;Homemade&rdquo; small optical thermostat and the pressure experiments are performed in a Diamond Anvil Cell (DAC).</span></p>
<p><span lang="EN-GB">The angular characterisation (sagittal and azimuthal) is assured by a motorised rotating system, allowing a high accuracy in angular positioning.</span></p>
