Abstract

In this paper, we report a diode end pumped laser with a Yb³⁺-doped Ca₄GdO(BO₃)₃ crystal (Yb:GdCOB). The dopant concentration of the crystal was 7%. The crystal was pumped longitudinally at 976nm by a fiber-coupled diode laser. The maximum output power of the laser emitted at 1.055um was 430mW, and the laser slope efficiency was 75% with respect to the absorbed pump power. We also observed that the output power still increased when the crystal no longer absorbed more pumped power (the crystal had been saturated). The possible reason may be that the thermal lens effect changed the distribution of the laser mode. This will be discussed in part 3.
