摘要
A Ti:sapphire-pumped Er3+:YLF laser is built. The samples are grown at our institute and are compared with a commercially available Er3+:YLF. The dopant concentration and the polarisation of the pump beam is optimised. Slope efficiencies up to 50% and thresholds as low as 42 mW are achieved. The emission properties of the laser are studied. The cw laser emission is linearly polarised. More than 90% of the output power is emitted on a single Stark transition.
