Mateusz Tyrk publishes in Optics Express
The results of Matt’s project developed within LA³NET have recently been published in the Optics Express journal. The work on Radially and azimuthally polarized laser induced shape transformation of embedded metallic nanoparticles in glass presents new findings in the field of reshaping metallic nanoparticles.
The paper presents the interaction of radially and azimuthally polarized ps-pulsed laser beams with glass containing spherical Ag nanoparticles. The authors used a Second Harmonic Generation cross-sectional scan method from silver nanoparticles in transmission geometry for characterization of the samples after laser modification.
The reshaping method presented in the paper adds an additional technique to shape manipulations of MGNs embedded in soda-lime glass. It expands the knowledge of already existing methods for versatile techniques of reshaping of nanoparticles with ultra-short laser pulses and can lead to nano-engineering of novel optical materials for applications in security and data storage.
