Calibration-Free Laser-Induced Breakdown Spectroscopy: State of the art …
1. Introduction. The Laser-Induced Breakdown Spectroscopy (LIBS) technique is, in brief, a mix of great potential and severe limitations. It offers a strong potential for analysis in situ and in real time, not requiring a separate sampling step. Since it does not need for sample preparation, it avoids wet chemistry.

The State-of-the-Art and Perspectives of Laser Ablation for …
The laser power range in CWs is between 2 and 30 W, and the treatment duration varies from a few minutes to 20 min. In PW mode, laser energy is released periodically as a sequence of pulses, and the pickup power (i.e., the power level of each pulse) is higher than that of CW emitting lasers, but the average power remains equivalent.
