ABSTRACT:
The present invention provides a method of mounting a light emitting element, in which a light emission point can be positioned at high accuracy with respect to the mounting member. A semiconductor laser element is placed on a matching stage. Next, a position and an azimuth of a laser stripe of the semiconductor laser element is observed, and linear displacement in X and Y directions of the semiconductor laser element from a reference line and a reference point on the matching stage, and angular displacement in an azimuth (θ) within an X-Y plane are measured. In accordance with a measured result, a control signal is sent to a driving mechanism of the feeding collet to drive the feeding collet, and the position of the semiconductor laser element is adjusted on the matching stage. After the adjustment, the semiconductor laser element is fed to and placed on a mounting surface of a heat sink H.
