蓝光激光技术与市场相适应过去５年中，在小型蓝光激光源“即将“推出的基础上已有众多“４倍光学数据存储密度”的报导。第一种蓝光器件以切会可夫倍频为基础。这种器件的蓝光输出令人瞩目，但器件效率和光束质量不佳，根据理论分析，这两个参数也不可能变得较好。最近，... Blu-ray Laser Technology Adapts to Market There have been numerous “4x optical data storage densities” based on the “forthcoming” introduction of small Blu-ray laser sources in the past five years. The first blue-light device is based on a cut-off frequency. The blue output of this device is remarkable, but the device efficiency and beam quality are poor. According to theoretical analysis, these two parameters can not be better. recent,...
