We report on the fabrication of an ultrahigh-quality-factor, bottle-like microresonator from a microcapillary and the realization of Raman lasing therein at pump wavelengths of 1.55 mu m and 780 nm. The dependence of the Raman laser threshold on the mode volume is investigated. The mode volume of the fundamental bottle mode is calculated and compared with that of a microsphere. Third-order cascaded Raman lasing was observed under pumping at 780 nm. In principle, Raman lasing in a hollow bottle-like microresonator can be used in sensing applications. As an example, we briefly discuss the possibility of a high-dynamic-range, high-resolution aerostatic pressure sensor. (C) 2015 The Japan Society of Applied Physics
