Optically pumped laser emission in K2 involving rovibrational levels near the B 1Πu state dissociation limit

Backward Raman amplification in the gas of rubidium dimers

“…We have developed a model and performed simulations that support this interpretation. Let us underline here that in this paper we study Raman gain, while lasing in dimers via optically pumped population inversion in the excited electronic states has previously been demonstrated in other dimers (see, for example, optically pumped lasers with Li 2 [15,16], Na 2 [15][16][17][18], K 2 [15,[19][20][21]). …”
