Fraunhofer-type absorption line splitting and polarization in confocal double-pulse laser induced plasma

Research output: Contribution to journal › Article › peer-review

Abstract

Strong line splitting and polarization are observed in Fraunhofer-type absorption lines in Pb, Sn, Si, Cd, In, and Zn in confocal double-pulse laser induced plasma (DP-LIP) experiments. This effect is detectable using medium laser power densities: (∼1-2) × 10¹³ W/m² for the first laser pulse and 1 × 10¹⁴ W/m² for the second laser pulse. Polarization and splitting effects exist only during the second laser pulse (∼7 ns). Absorption line polarization and splitting phenomena may be explained by a high overall magnetic field and motional Stark effect caused by the second laser pulse inside the laser plasma created by the first pulse.
