Title: Semiconductor laser diode assembly apparatus
Inventor: LEE JAE HO
IPC: H01S3/05
Filed: 1993-10-27
Granted: 2000-09-15
Abstract: PURPOSE: An assembling device of a semiconductor laser diode is provided to make the axial of the laser beam to project the beam passing exactly the axial of the package and thus to increase assembly yield. CONSTITUTION: In the device of assembling semiconductor laser diode, a sub-mount fixing tool(11) is prepared on the upper part to hold tight the sub-mount(12) while attaching a laser diode chip(13) to the sub-mount(12). A collet(14) is formed above the fixing tool(11) to hold, rotate and move side to side and back and force the laser diode chip(13). A die(18) for aligning is attached on one side of the fixing tool(11) to fix the laser diode(18) for excitation and the light sensor for light receiving(17). A processing unit amplifies the signal from the light sensor(17) and displays the amplified signal on the monitor.
