Abstract

The application of heterostructure lasers to video disk systems is described. The buried heterostructure diode laser is used as a light source of the optical pickup for the optical video disks. This pickup enables video signals to be reproduced with a SNR of more than 40 dB. These lasers can be not only used as a light source to read out the signal from the disk but also as a detector of the reflected light.

摘要

描述了异质结构激光器在视频磁盘系统中的应用。掩埋异质结构二极管激光器用作光学视频磁盘光学拾取器的光源。这种拾取器能够以超过40dB的信噪比再现视频信号。这些激光器不仅可以用作从磁盘读出信号的光源，还可以用作反射光的探测器。
