摘要：

Laser action, tunable around 1.2-mu-m, has been reported in Cr-activated forsterite (Mg2SiO4). We have examined the emission from this material in the region 650-850 nm via photoluminescence, excitation and lifetime studies over a range of temperature. Our measurements indicate that the emission in this region can be assigned to transitions on Cr3+ ions in high-field octahedral sites. The emission from the M1 site is clearly identified. We propose a simple model to account for the temperature dependence of the luminescence.
