Paper Abstract

The oscillation wavelength of a Nd3+-doped tellurite glass microsphere laser is controlled using a λΑ/4-shifted grating fabricated on the surface of the microsphere. The lasing wavelength is in agreement with the high transmission wavelength of the grating estimated from the grating period and the effective index of the whispering gallery mode.
