Abstract
The applied Boltzmann relaxation kinetics for stationary and ps-pulsed nonresonant pumping takes the polariton-acoustic phonon and the polariton-polariton scattering into account. For cavities with a vacuum Rabi splitting around Ω=8meV, we find for ps-pulse excitation a transient bosonic condensation in the ground state. For microcavities with a large vacuum Rabi splitting of Ω=26meV we find for zero detuning, due to the steep increase of radiative losses, a condensation with a macroscopically occupied state in the wavenumber region at which the Bragg mirrors become transparent. With positive detunings which increase the scattering rates, the finite-size Bose-Einstein condensation in the ground state is restored.
