The results show: pulse power density from CO2 laser reaches air breakdown threshold through thrice reflecting focus system, and plasma radiation phenomena is observed in the experiment.
The Association's global and regional steering committees bring together industry experts to focus on important issues relating to the quality, safety and efficacy of plasma therapeutics.
