DOI: 10.1017/jfm.2019.1066
Abstract: A focused laser can cause local optical breakdown of a gas, which leads to rapid deposition of energy into a high-temperature plasma kernel that expands and induces a complex flow. For some conditions, hot gas… read more here.

DOI: 10.1364/oe.27.008456
Abstract: When a femtosecond laser pulse propagates through water clouds, optical breakdown can occur once the laser intensity exceeds a certain threshold. This photoionization process, along with the resultant laser-induced plasma, can strongly influence laser communications… read more here.
