One order or greater of magnitude enhancement of lasing emission is confirmed experimentally from liquid microdroplets of Acridine Orange dye mixed with the fat emulsion Intralipid-10% suspension as highly scattering media, compared with pure dye-doped droplets. This novel method that makes use of a high-gain laser dye soft scatter microsystem allows for a wide range of lasing of microdropslets. Originally without lasing pure dye droplets enabled one to lase with a well-defined threshold and an appreciably increased emission intensity in suitable conditions. Spectral characteristics and emission peak intensities from these microdroplets are measured quantitatively as a function of volume content of Intralipid-10% solutions.
