以RLD-78MA为例 介绍激光二极管的性能:beam epitaxy (MBE) which has excellent control features and our development of an SAM laser with an ideal laser structure, we have succeeded in the hitherto unthinkable mass production of our RLD series of laser diodes. An example which compares the dispersion of q^ and q/ / characteristics of our RLD-78MA with a previous product is shown in Fig. 9. Dispersion has been reduced to less than one-third that of the previous product, and this tight dispersion range means that we can consistently supply large quantities of laser diodes which are optimum for the target application.
