The frequency doubled Nd:YAG-pumped performance of two pyrromethene-BF2 complex laser dyes in a modified acrylic polymer host is described in detail. Optimization experiments included changes in output coupler reflectivity and determination of the slope efficiency in a simple end-pumped oscillator cavity. A slope efficiency of 88.8% was achieved for the PM- 567 laser dye in the solid host.
