Here, lasing on the D₁ transition (6²P_1/2 → 6²S_1/2) of cesium can be reached in both diode and excimer pumped alkali lasers. The first uses D₂ transition (6²S_1/2 → 6²P_3/2) for pumping, whereas the second is pumped by photoexcitation of ground state Cs-Ar collisional pairs and subsequent dissociation of diatomic, electronically-excited CsAr molecules (excimers). Despite lasing on the same D₁ transition, differences in pumping schemes enables chemical pathways and characteristic timescales unique for each system. We investigate unavoidable plasma formation during operation of both systems side by side in Ar/C₂H₆/Cs.
