1. A resonator for a laser oscillation system including a laser cavity for laser oscillation, the resonator comprising: a saturable absorption layer formed on a support and a tapered fiber disposed around at least part of the support to be adjacent to the saturable absorption layer, wherein the tapered fiber is formed so that directions of an optical path of a part extending from one end of the tapered fiber and another optical path of another part extending from the other end are different from each other, wherein the support is made of a material which changes in size by reaction with heat, the saturable absorption layer generates heat when absorbing light, and a repetition rate of the output light from the tapered fiber is adjusted by the heat induced size change of the support.
