摘要: Abstract The photodissociation lasers of K2 from 1 to 4 μm have been studied in a heat-pipe oven. Laser emission occurs on the K (4F→3D) transitions at 1.5 μm, (6S 2 →5P 3 ) transition 3.66 (4D→5P) 3.71 and 3.373 (5P→5S) 2.7 (5P→3D) 3.14 3.16 (5S→4P) 1.24 1.25 K(3D→4P) 1.17 1.18 μm. laser emissions K(4F), K(6S), K(4D), K(5S), K(3D) states not previously reported connection with lasers. Atomic are populated by two-photon pulsed excitation (X1Σg+) molecules excited molecular that selectivity dissociate ground state atom plus or K(5P) atom. most intense when oven is operated mode pressures between 10 Torr, which corresponds temperatures 375 430°C.
