日本松下电器产业公司用红色半导体激光器首次成功从1芯片获得2束激光。在芯片上使2个半导体激光器集成,而分别放在材料的两面,使其不受放热的影响互相不受干涉,与过去的红外半导体激光器相比数字传输实现了高速化改写读存取操作,将来高的速度是以前的2.6倍,如果与高密度大容量光盘相组合的话,期望光盘系统成为高像质的图像记录装置。 Matsushita Electric Industrial Co., Ltd. successfully obtained two lasers from a single chip for the first time using a red semiconductor laser. Two semiconductor lasers are integrated on the chip and placed on both sides of the material independently of the exothermic effect. The digital transmission is faster than that of the past infrared semiconductor lasers, and the read access operation is rewritten In the future, the high speed is 2.6 times that of the previous ones. If combined with a high-density, large-capacity optical disc, the optical disc system is expected to be a high-quality image recording apparatus.
