Laser spectroscopy – examinations with laser light
Scientists always want to know every little detail. That is why they study correlations, compositions, reactions and their consequences, and so on. Laser spectroscopy helps them with this.
This is a physical method using laser light as a physical medium to examine substances, or matter. In short: They screen matter to determine how the matter interacts with the laser or reacts to it.
Surely you are asking yourself – what is the point? Could we not just leave the matter alone? It is not normally screened by laser light, so why do we need to know how it reacts?
Let us take a look at medicine. Laser spectroscopy has been used actively in that field for many years, practically daily, to make really tiny objects, e.g. tissue, visible.
Laser spectroscopy is based on the principle of fluorescence spectroscopy. It uses the ability of matter to absorb light and emit it again in another form.
Another aspect is important for doctors and scientists: The processes in the human body, for example in muscle tissue, happen so unbelievably fast that they could not be seen and therefore not be understood without the use of laser spectroscopy. So we would miss out on crucial knowledge which is needed to establish certain connections.
