Determination of molybdenum ablation threshold for ultrashiort laser pulses in atmosphere and vacuum using the diagonal scan technique
2010 - SAMAD, RICARDO E.; VIDAL, JOSE T.; ROSSI, WAGNER de; VIEIRA JUNIOR, NILSON D.
We present the results of measuring metallic molybdenum ablation threshold in the 30 femtoseconds regime. The measurements were performed in atmosphere and vacuum, resulting in values equal to 1.6 TW/cm2 3.8 TW/cm2, respectively. This values difference can be credited to a plasma etching that helps the ablation in the atmosphere case.
