Abstract

The possibility of using stimulated emission to improve the optical pumping of Tm3+ ions embedded in Tm3+:YAG to the 3F4 level is explored. The oscillator strengths and the frequencies of the transitions between the ground crystal field level of 3H4 to the different crystal field levels of 3F4 are measured at low temperature. Stimulated emission measurements at 1461 nm are performed to evaluate the optical pumping efficiency. Application to the spectral tailoring of Tm3+:YAG for quantum information applications is discussed.
