Presented at ICALEO 2012
Performance of various modern laser based micromachining techniques can be improved by applying square laser spots with uniform intensity distribution. And providing possibility of scanning of such a spot over whole working field with using popular 2- and 3-axis galvo mirror scanners is of great importance for many laser microprocessing technologies, like scribing, drilling holes in PCB, repair techniques in display making technolog...$28.00

Presented at ICALEO 2012
The biodegradable polymer such as poly(L-lactic acid) (PLLA) is promising in drug delivery applications because it hydrolyzes into non-toxic substances in physiological environments. However, its induction period of biodegradation prevents the embedded drugs from releasing at the designed rate in the...$28.00

Presented at ICALEO 2012
The production of nanometer-scale features on platinum samples was investigated with the use of a femtosecond laser system operational at IR, visible and UV wavelengths. Laser induced surface structures were produced having globular nanoprotrusions with apparent length scales ranging from sub-nanometer diameters to 100s of nanometers, dependent on the laser parameters employed. Analysis of Field Emissi...$28.00
