Abstract

The effect of substituting deuterium for hydrogen in EuCl ₃·6H ₂O on the lifetime and homogeneous and inhomogeneous linewidths of the ⁷F ₀→ ⁵D ₀ transition at below 4 K are investigated. It is observed that the transition lifetime increases from 116μs to 2.6 ms and the homogeneous linewidth decreases from 4.1 kHz to 430 Hz. The sensitivity of the inhomogeneous broadening to the residual hydrogen concentration is estimated to be 91 MHz/atm%. The potential of utilizing this crystal for quantum memory applications is discussed.
