To fix precisely by laser wedding between an optical collimator and a main body of optical components, automatically laser trimming technique has been achieved by non-contact processing for the passive optical components. This control system is consists of a pulsed YAG laser and an optical power monitor only as simple configuration. From starting program, it spends a time within 150 seconds and forty welding points at most to produce the completed components in laser trimming processing.
