Example Embodiment
[0015] The beam compression process of the present invention is as figure 1 As shown, the specific process is as follows:
[0016] The TO tube socket 3 adopts the existing general structure, including a tube shell, a tube tongue and a tube pin, and the tube tongue is in the shape of a six-sided column. First evaporate the solder on the tube tongue as usual, then bond the semiconductor laser chip in the middle of the tube tongue so that the light-emitting cavity surface of the chip is flush with the upper end surface of the tube tongue, and then alloy at 180℃, and then bond Hehe Optoelectronics Testing.
[0017] Then use the cap 2 corresponding to the model of the TO socket 3 to package the cap 2 on the TO socket 3, and the cap 2 is in the middle of the socket 3, that is, the center line of the cap coincides with the center line of the socket.
[0018] Adhere the cylindrical lens 1 to the outside of the cap 2, such as figure 2 As shown, the cylindrical lens 1 is parallel to the cavi...
