摘要：
We report the first observation of the resolved structure in the I-4(15/2) --> I-4(13/2) infrared transition of LiYF4:Er caused by lithium isotopes of the lattice. Isotope shifts of 0.019 and 0.016 cm(-1) and inhomogeneous linewidths of 0.010 and 0.007 cm(-1) were measured for the lines 6534.3 and 6538.3 cm(-1), respectively. Unresolved structure due to different erbium isotopes totals similar to 0.010 cm(-1). (C) 2000 Elsevier Science B.V. All rights reserved.
