Results of consideration for bimodal laser regime in aerosol micro particle under the action of the second harmonic of a Nd-doped power glass laser as a pumping source for the mixture of an active substance and a saturable absorber as micro impurity in a spherical micro particle are proposed. Bimodal radiation in aerosol microparticle as spherical cavityis considered. Interactions of modes in presence of impurity as absorber both and enlargement and inhibition effects aredescribed to enlarge sensitivity to impurity.Keywords : microsphere. aerosol, saturable absorber, microimpurity, whispering gallery mode. 1. INTRODUCTION Nonlinear interactions and laser oscillations in dielectric aerosol micro droplet with weak absorption attract attention due to extremely high quality of quasi normal modes in such meso-cavities. High sensitivity of modal radiation to absorbing permits us to found reliable method for detection of pollution in atmosphere and enviromental medium as micro impuritiesin an aerosol micro droplet.for practical application in information processing systems due to their fitting to other opticalelements and concentration of high energy in small volume, what permits us to preserve energy and materials.
