| Abstract: | Semiconductor laser technology is an improtant opticelectric element and its beam quality improvement is significant to the application of semiconductor laser. Several new laser beam quality improvement technologies are discussed. It includes the astigmatic gradient index lens basing on the theory of diffraction, the reflection elements basing on the reflection theory and some other optical systems relying on multi theory, etc. Several new technologies appearing domestically and abroad recently such as astigmatic gradient index elements, liquid cell and single reflection device are emphasized. |
