日前,Intel公司首次研制出了1850nm的硅基拉曼级联激光器。这种激光器效能好,能在室温运转,且能用于许多日常器件上。级联激发是拉曼激光器的独特特性,能得到常规激光器很难实现的激光波段。2005年2月,Intel公司首次演示了运转在1686nm波段的连续波硅拉曼激光器,此后,他们改进 Recently, Intel Corporation for the first time developed a 1850nm Si-based Raman cascade laser. This laser is efficient, can operate at room temperature, and can be used on many everyday devices. Cascading excitation is a unique feature of Raman lasers that provide the laser band that is difficult to achieve with conventional lasers. In February 2005, Intel Corporation demonstrated for the first time a continuous-wave Si Raman laser operating in the 1686-nm band, and since then they have improved
