Cree研究公司演示了一台在常温下运行的蓝色半导体二极管脉冲激光器，将其应用于商业设备上将会极大提高光存储容量．该公司生产的403urn激光器是以碳化硅做衬底和氮化像做激光介质．1995年日本Nichia化学工业公司曾演示过以蓝宝石做衬底的氯化筹二极管激光器，但Cree公司的激
Cree Research demonstrated a blue semiconductor diode pulsed laser operating at room temperature, which would greatly increase the optical storage capacity when applied to commercial equipment. The company’s 403urn laser is made of silicon carbide substrate and nitride like laser medium. In 1995 Nichia Chemical Industries of Japan demonstrated a diode lasing diode made of sapphire substrate, but Cree’s excitement
