In conclusion, when a MOT of actively driven atoms is collectively strongly coupled to a Fabry-Pérot cavity, lasing is seen in the red detuned emitted light from the atom-cavity system. The lasing for a stabilized cavity and MOT atom number is continuous in nature. This driving field is the same as the MOT light which cools and traps the atoms and results in continuous operation of the laser from the coupled atom-cavity system. The lasing is seen for the red detuned peak because symmetry is broken in favour of the red detuned peak due to the MOT light, which also confines the atoms effectively and couples it to the cavity mode. In principle the lasing could be achieved on the blue detuned peak if the driving frequency and the trap mechanism were not connected and the driving light was blue detuned with respect to the atomic transition. The observed phenomena are therefore generic to the driven atom-cavity system and have potential to be of interest for basic studies and for applications. To analyse the basic processes of this phenomena a semiclassical theory of light-matter interaction is presented in the discussion section and appendix, where the role of Mollow
