Thank Simon and Andy for your answers but let me explain a little bit more my goal.
I understand laser light is monochromatic, collimated and coherent and at least some of these properties are desirable for a good optical trap, however I have some reasons to pursue in my objective.
I need to...
Optical traps for refractive colloidal particles (latex) of around 1 micron always employ a laser ligth tipically of 30 mW or even less. I have never seen a report of an optical trap using a non-laser light source. I wonder if is possible to build a non-laser light optical trap and if not why. I...
