Optically pumped NO(A 2Σ+→X2#7B-P) ultraviolet laser

Lasing action on the (0,1) and (0,2) γ bands of NO at 237 and 248 nm, respectively, has been obtained by longitudinal pumping of 0.5 Torr of NO on the (0,0) γ-band transition at 227 nm. Typical output pulse energies were 13 μJ at an intrinsic energy conversion efficiency of approximately 15%.
