The technology of XeF(C-A) laser pumped by two counter optical sources is discussed and the photographes of the XeF2 photodissociation waves propagating from two directions are given. The output energy of XeF(C-A) laser is enhanced under two pump sources condition, which is 3.3 J with the laser pulse duration of 1 100 ns. The output properties of XeF(C-A) laser are obviously affected by the initial XeF2 concentration. The laser formation time increases with the increase of the initial XeF2 concentration and the near-field pattern of the laser beams has different profiles under different XeF2 concentration.
