Strong laser-like emission from polaritons in microcavities has been observed and attributed to bosonic enhancement in the emission process (Snellart and Bloch, 1999; Savvidis et al, 2000; Erland et al, 2000). This relies on the bosonic nature of low-density polaritons stimulating the scattering processes by the final-state polariton population. Strong enhancements of the scattering processes have been observed as a result of up to several 100 polaritons per final k-state under angle-resonant pumping conditions (Erland et al, 2000; Stevenson et al, 2000). Energy and wave vector are conserved in the angle-resonant process by scattering of two k/sub ËË/=k/sub ËË,res/ polaritons into 2k/sub ËË,res/ and k/sub ËË/å0 states, respectively, the latter resulting in the strong secondary emission that is studied in this work.
