Laser processing of dielectric materials with ultrashort pulses is often considered to be free of thermal damage. Yet, in practice a thin heat-affected layer is formed underneath the ablation crater. Researchers at the CSIC in Madrid have developed a method to observe the formation of this layer with time resolution. #APLEP http://tinyurl.com/zqk96xe | Applied Physics Letters

This is how the world’s most powerful laser can simulate a planet’s core
