Find out the laser power density in watts

Reference no: EM13684559

A sample being examined by laser ablation-inductively coupled plasma-mass spectrometry has a density of 4.07 g/mL. After a 19.0-ns laser pulse a crater with a diameter of 33.4 m and a depth of 1.269 m was created. If the energy of the laser pulse was 2.68mJ,
