Abstract :
Absorption cross sections of Cr3+in the metastable2E states of pink ruby (0.05 percent Cr2 O3 ) have been measured for 
between 4000 Å and 7000 Å at 297°K and 115°K. Both 0 degree and 90 degree ruby rods were measured in a flash absorption apparatus having a spectral resolution of 50 Å. The broad excited state absorption bands centered at 5600 Å appear to correlate with the positions of2T1 (3T1 ) level, while the narrow band centered at 4540 Å correlates well with the predicted2A2 (1 
) level. The effect of excited state absorption on laser operation is discussed in this paper.
