Abstract

We have measured the laser-induced breakdown (LIB) thresholds in water using an artificial eye for chirped and non-chirped laser pulses at 44 fs and 810 nm. We compare these measured thresholds to calculated values for a range of pulse widths from 20 fs to 120 fs and for various focal point diameters. The LIB threshold using a flat phase pulse, i.e., no chirped compensation for propagation through the water was measured to be 0.285 (0.280 - 0.290) μJ. Using a pre-chirp on the laser pulse, the LIB threshold dropped by one-third to 0.192 (0.191 - 0.194) μJ.
