Correlation between ablation efficiency, surface morphology, and multipass capability using a 100-W 10-MHz ultrafast laser

Autor: Eric Mottay, R. Kling, K. Mishchik, G. Mincuzzi, Eric Audouard, John Lopez

Publikováno v: Laser Applications in Microelectronic and Optoelectronic Manufacturing (LAMOM) XXIII.

Nowadays the relevance and the robustness of ultrafast lasers are well established for many industrial applications. Indeed this laser technology combines the unique capacity to process any type of material with an outstanding processing precision an

Laser glass cutting by spatio-temporal control of energy deposition using bursts of femtosecond pulses

Autor: K. Mishchik, R. Kling, Bruno Chassagne, O. Dematteo Caulier, Clemens Hoenninger, John Lopez, Eric Mottay, Guillaume Duchateau

Publikováno v: Conference on Lasers and Electro-Optics.

We demonstrate the beneficial effect of femtosecond bursts for energy concentration during volume processing of transparent material. By single pulse energy redistribution in burst sub-pulses, nonlinear effects can be significantly reduced. A 25 ns t

Optimization of the Energy Deposition in Glasses with Temporally-Shaped Femtosecond Laser Pulses

Autor: K. Mishchik, Ingolf V. Hertel, Razvan Stoian, Eric Audouard, Arkadi Rosenfeld, Alexandre Mermillod-Blondin, Cyril Mauclair

Publikováno v: Physics Procedia
Physics Procedia, Elsevier, 2011, 12, pp.76-81. ⟨10.1016/j.phpro.2011.03.108⟩

International audience; Bulk machining of glasses with femtosecond laser pulses enables the fabrication of embedded optical functions. Due to the nonlinear character of the laser-matter interaction, structural modifications can occur within the focal

3D adaptive spatio-temporal control of laser-induced refractive index changes in optical glasses

Autor: Ingolf V. Hertel, Alexandre Mermillod-Blondin, E. Audouard, Arkadi Rosenfeld, K. Mishchik, Guanghua Cheng, Cyril Mauclair, Razvan Stoian

Publikováno v: SPIE Proceedings.

The nonlinear absorption character determines a high potential of ultrafast laser pulses for 3D processing of transparent materials, particularly for optical functions. This is based on refractive index engineering involving thermo-mechanical, and st

Time-resolved observation of energy deposition in fused silica by utrashort laser pulses in single and cumulative regime

Autor: Cyril Mauclair, K. Mishchik, Alexandre Mermillod-Blondin, Ingolf V. Hertel, Jörn Bonse, Arkadi Rosenfeld, Razvan Stoian, Eric Audouard

Conference on Lasers and Electro-Optics (CLEO), May 2010, San José, CA, United States. pp.CMBB7

International audience; When femtosecond laser pulses are focused in the bulk of transparent materials (glasses), deposition of energy on a restricted volume can occur owing to the non linear character of the laser matter interaction. As a consequenc
