Ultrafast laser processing of materials: a review
Advances in Optics and Photonics, 2015We present an overview of the different processes that can result from focusing an ultrafast laser light in the femtosecond–nanosecond time regime on a host of materials, e.g., metals, semiconductors, and insulators. We summarize the physical processes and surface and bulk applications and highlight how femtosecond lasers can be used to process various

Ultrafast laser processing and metrology
CLEO: 2014, 2014Precisely controlled blind via-holes were formed in multilayer substrates by an ultrafast laser. A LIBS detector integrated into the laser processing machine realizes the full potential of the ultrafast laser.

Ultrafast Laser Processes for Photonics
Optical Fiber Communication Conference (OFC) 2019, 2019Space division multiplexing (SDM) has the potential to dramatically increase the information capacity of single optical fibres. I will review how ultrafast laser processing techniques can be used to fabricate interconnect components for SDM applications.

Ultrafast laser processing of diamond
SPIE Proceedings, 2014Ultrashort pulsed lasers are used to fabricate 3D structures in single crystal CVD diamond. The interaction of the laser with diamond lattice leads to a permanent structural modification, which is highly localized at the focus. Severe spherical aberrations compromise fabrication precision below the diamond surface.

Ultrafast lasers for nanomaterial growth and processing
2007 European Conference on Lasers and Electro-Optics and the International Quantum Electronics Conference, 2006Laser ablation is a well-established solid-state film growth technique that typically involves applying a nanosecond laser beam to ablate a target material, followed by depositing the precursor vapor onto a substrate. A main technical obstacle for growing thin films with conventional nanosecond laser ablation is the formation of micron-sized ...

Biological processes studied by ultrafast laser techniques
1988In writing this review of fast kinetic and spectroscopic studies in biology we have attempted to put the new pulsed laser results into a broad biological context. In this way it is hoped that those not so familiar with the biology will be familiarized with at least a few of the basic questions that modern laser technology might address.

Ultrafast laser trepanning process and modeling
ICALEO 2016: 35th International Congress on Applications of Lasers & Electro-Optics, 2016We present an engineering model of ultrafast laser ablation with normal or non-normal (oblique) laser beams. It can be applied to trepanning drilling but also to zero-taper cutting. Specific experiments on line ablation are presented to understand how oblique beams can control the walls conicity.

Ultrafast Laser Processing of Semiconductor Devices
CLEO:2011 - Laser Applications to Photonic Applications, 2011SiOnyx is developing ultrafast laser processing techniques that improve the performance of semiconductor based photodetectors, solar cells, and image sensors. Ultrafast laser processing offers the unique ability to locally engineer the structural and doping characteristics of semiconductor devices and avoid adverse side effects.
