Tunable radiation with a linewidth of 0.014 nm was obtained in Rhodamine B,
Rhodamine 6G, Perylene orange and Pyrromethene 567-doped GPTMS solid-state
dye materials using intracavity grating dispersive oscillation. The solid
dye samples were specially designed in the way in which they are gelling, d
rying and ageing between two anti-reflection coated disks, thus without any
mechanical and optical processing. The conversion efficiency of 4.6% and t
he tunable range of 40 nm from 589-629 nm have been achieved in Rhodamine B
-doped samples. The broadband lasing of 4.4 nm and 54% slope efficiency wer
e also demonstrated in the experiment.
