Abstract(in English) In an optical system of inline type lider, a device must be installed to separate transmitting laser beam and echo signal.In this study, an optical circulator is applied to solve this problem.This optical circulator enables to separate transmitting the beam and the echo signals, and also to divide the echoes with the orthogonally polarized components.It is light weight and compact size(weight 1.3kg・all sides of 30cm).The insertion loss is 3dB at wavelength 1.047μm.And it is attached to an optical tube of a telescope.Moreover, an optical axis of the circulator is not run off even if the telescope is operated.
