Realization of a high energy, high beam quality CO2 laser using a SFUR cavity

We have obtained a source with a high beam qualty and output energy, which could be useful for laser-surface interaction studies. A very promising injection method has been tested in a very critical configuration, giving very good results. We believe that, when adopting either PZT cavity tuning, or higher injection power, or a shorter pulsed cavity, a very high frequency selectivity can be achieved, coupled with the same CW source insulation that we verified in this work.
