Multi-axis motion systems for surface nanotexturing, micromachining, 3-dimensional structure fabrication, and laser-matter interaction studies.
EF 2013-14
Résumé
Funds are requested for purchasing two multi-axis motion systems, one for ultrahigh precision positioning and the other one for high speed motion over large distances. These motion systems will be used in combination with an already available femtosecond laser and will support the research programs of the ten applicants on this proposal in the following areas: i) surface micro and nanotexturing, ii) micromachining, iii) three-dimensional structure fabrication, and iv) laser-matter interactions.i) The motion system includes galvo mirrors which allow for high speed scanning of the sample surface to create nanoscale features over large areas. These surface modifications will be used for improving the bio-compatibility of metallic implants and for creating controlled optical effects such as holograms.ii) The motion system, when combined with the femtosecond laser, will be ideal for shaping reactive materials that would otherwise react upon heating using conventional machining techniques. The proposed high resolution motion system will also permit miniature samples to be extracted from bulk materials and provide information on local mechanical properties which is a key element in our effort towards predicting the deformation and fracture of metals, polymers and biomaterials. Precise positioning will also allow precise material removal during machining to tune piezoelectric energy harvesters to the adequate vibration frequencies.iii) This unique facility will allow the creation of new devices such as microlenses with complex three-dimensional shapes. The motion system combined with the ability of femtosecond lasers to modify the bulk of transparent materials will be essential to fabricate three-dimensional micro-channels in bulk glasses and polymers for studies on blood micro-fluidics.iv) Finally, the proposed system will allow a better understanding of laser-matter interactions and will provide the experimental results required to assess the validity of theoretical models.
