HIGHLY SCATTERING INTRALIPID-10-PERCENT ASSISTED LASING FROM MICRODROPLETS WITH ACRIDINE-ORANGE DYE

One order or greater of magnitude enhancement of lasing emission is co nfirmed experimentally from liquid microdroplets of Acridine Orange dy e mixed with the fat emulsion Intralipid-10% suspension as highly scat tering media, compared with pure dye-doped droplets. This novel method that makes use of a high-gain laser dye soft scatter microsystem allo ws for a wide range of lasing of microdropslets. Originally without la sing pure dye droplets enabled one to lase with a well-defined thresho ld and an appreciably increased emission intensity in suitable conditi ons. Spectral characteristics and emission peak intensities from these microdroplets are measured quantitatively as a function of volume con tent of Intralipid-10% solutions.
