Below threshold, very few photons will be emitted into the lasing mode, but above threshold most of the photons will be emitted in the lasing mode. The photon generation rate in the lasing mode is given by. To calculate the photon density in the cavity, we need to calculate firstly the photon lifetime. The photon density is now. 2005/06 ................
