Ultrafast Laser Modification of Materials

Submission Deadline: 1 July 2013
Publish Date: 1 October 2013

Using recent progress in laser technology and in particular in the field of ultrafast lasers, we are getting close to accomplish the alchemist dream of transforming materials.

Compact lasers can generate pulses with ultra-high peak powers in the Tera-Watt ranges. These high-power pulses lead to a radically different laser-matter interaction than the one obtained with conventional lasers. Nonlinear processes are observed leading to new and exciting opportunities to tailor the matter in its intimate structure with sub-wavelength spatial resolutions and in the three dimensions.

This new way of processing material has numerous potential applications not only in integrated optics (waveguide writing, novel polarization devices, Bragg gratings, devices for future quantum communications, etc.) but also for optomechanics (sensors, actuators, etc.) and optofluidics (lab-on-a-chips). No other technique holds the same potential to realize 3D multi-functional photonic devices, fabricated in a single step in such a wide range of transparent materials. It exhibits enormous potential in the development of a new generation of powerful components.

This field of research is still at its infancy. Numerous aspects of the non-ablative laser-matter interaction (below the ablation regime) have yet to be understood and its full application potential has yet to be unravelled. This approach, using out-of-equilibrium synthesis and processing with laser beams, opens new ways to create functional materials and devices that are difficult whether not possible to achieve with current established techniques. This new field relies on the investigation of laser-material interaction and photo-chemical processes. The understanding of the involved physical phenomena, their associated characteristic times, and the resulting phase or structural modifications is of particular importance.

This special issue will cover the science and technology of ultrafast laser modification of materials, from the fundamentals - the interaction of ultrafast non-ablative pulses with dielectrics and other transparent materials - to the applications in various technological fields.

Original articles related to the themes of Ultrafast Laser Modification of Materials are invited in a range of topics including but not limited to the following:

  • Non-ablative ultrafast laser-matter interaction in dielectrics and polymers
  • Defects and microstructures formation resulting from ultrafast laser exposure
  • Mechanisms of formation for self-organized nanostructures
  • Surface modifications and mechanism for ripples formation
  • Optical properties of laser modified structures

All papers need to present original, previously unpublished work, and will be subject to the normal standards and peer-review process of the journal. Papers will appear in the Optical Materials Express journal and will be published online upon acceptance.

Manuscripts must be prepared according to the usual standards for submission to Optical Materials Express and must be uploaded through OSA's electronic submission system. When submitting, please specify that the manuscript is for the Ultrafast Laser Modification of Materials feature issue (choose from the drop-down menu). Please note that submissions to this feature issue incur the normal OMEx publication fee.
