An X-ray photoswitched XeC1 laser is described with an emphasis on the physical processes with determine its behaviour. A short pulse duration, 5 ns, has been used to phototrigger a 50 cm3 active volume laser head. To gain insight into the avalanche processes, the breakdown delay times have been measured and compared to the theoretical values obtained from a code assuming a local field approximation. A specific laser energy higher than 6 J/L with an effiency of 2 % is reported. The duration of the laser pulse is 30 ns leading to a specific extracted power higher than 200 MW/L.
