Abstract
The paper reports on the development of optical coherent transient techniques to efficiently build a single frequency sample. These techniques are tested in a Tm/sup 3+/:YAG crystal cooled at 4 K or immersed in superfluid helium. All experiments are concentrating on optically driven population transfer from ground state /sup 3/H/sub 6/ to upper state /sup 3/H/sub 4/ and back. This two-level system is complemented by level /sup 3/F/sub 4/, a metastable shelving state connected to the upper level by a nonradiative transition.
