Abstract

PURPOSE:To radiate laser beams in multiple directions by mounting semiconductor laser elements on respective holding plates of a support base which has multi-stage holding plates. CONSTITUTION:The semiconductor laser elements 8 are mounted on respective holding plates of the support base 7 which is equipped with multi-stage holding plates 6 in such a manner as each element can radiate laser beams in different direction each other. This feature allows laser radiation to be performed in multiple directions and makes frequency division multiplex communication possible when laser diodes of different wave lengths are used.
