A continuous wave laser excites a biological particle. Detection channels are created to detect light scattered by the biological particle, and to detect any auto-fluorescence emitted by the biological particle. Additional channels can also detect light emitted by auto-fluorescence of the biological particle when simultaneously excited by light at harmonics of the laser's fundamental wavelength. The biological particle is identified using Mie scattering and auto-fluorescence. Ratio-metric calculations generated by calculating ratios of detected peak heights or integrated pulse values in the channels provides additional information for identifying and classifying the biological particle. A warning or alert can be provided if the identified biological particle is a particle of interest.
