Abstract
A small spherical dye laser containing rhodamine 6G pumped by a compact TEA UV-N2 laser is reported. Small spheres of good quality are observed under the microscope. The lasing characteristics of the spherical dye laser are different from the usual bulk dye laser, with respect to the direction of the laser beam. The former is oriented in all directions while the latter is unidirectional. The waveform and spectral characteristics from the dye-doped small spheres show lasing in the whispering-gallery modes.Keywords
