Analysis of the influence of absorption on spatial field structures of morphology-dependent resonances in cylindrical microparticles.

Morphology-dependent resonances in cylindrical microparticles are investigated and the properties of particle matter considered. The spatial structures of resonance modes inside microparticles are studied. It is shown that the resonant mode with a lesser quality factor can have a higher value of internal field intensity inside microparticles.

Thermal effect of pumping intensity on the active medium of a neodymium:glass microlaser.

We theoretically investigated the influence of pumping intensity radiation on the active medium of a neodymium:glass microlaser. The pumping radiation in the neodymium:glass microlaser causes heating of the active medium to the softening temperature. The time necessary for the heating is estimated; it changes from fractions of nanoseconds to hundreds of microseconds.
