Influence of Inter-Pulse Delay and Geometric Constraints on Damage and Optical Characteristics in thin Metal Targets Irradiated by Double Ultrashort Laser Pulses
George D. Tsibidis
Femtosecond pulsed laser systems constitute powerful tools for the high-precision structuring of materials at micro/nano-scale resolutions. A critical parameter influencing the eff…
Fabrication of highly uniform laser-induced periodic structures on polycarbonate via UV femtosecond pulses
Matina Vlahou, Nektaria Protopapa, Stella Maragkaki +2
In this work, we focus on the fabrication of highly uniform laser-induced periodic surface structures (LIPSS) on bulk polycarbonate (PC) using 258 nm femtosecond laser pulses. A sy…
Deciphering Carrier Dynamics in Polycarbonate Following Excitation with Ultrashort Laser Pulses
George D. Tsibidis, Matina Vlahou, Stella Maragkaki +2
Polymers exposed to ultrashort pulsed lasers (UPL) experience a range of physical and chemical changes that play a key role in applications ranging from material processing to adva…
Control of the damage threshold of Si via a SiO2 coating upon irradiation with Mid-IR femtosecond laser pulses
George D. Tsibidis, Emmanuel Stratakis
A key issue in the use of high-power mid-infrared (Mid-IR) laser sources for a plethora of applications is the investigation of the exciting laser driven physical phenomena taking…
