Recently, compact efficient RGB (red, green, blue) lasers have attracted much attention due to the strong demand in the fields of bio-instrumentation and laser projection. Rapid growth in the biotechnology instrumentation market is creating unexpected applications such as in DNA and cell analysis. The market for lasers used in bio-instrumentation applications is estimated to be in excess of $470 millions for 2007 according to a market forecast by Laser Focus World, 2006. It is estimated that the market of lasers for these applications will reach about US$1 billion in 2012. In the field of laser projection, compact red, green, blue (RGB) lasers with an output power from several milliwatts to watts are required. However, green semiconductor laser diodes (LDs) are not available due to the lack of suitable materials, and output power from the available blue LDs are not sufficient and beam shape from the available red LDs are not good enough for laser projection. According to Insight Media, the total laser display market will reach US$2.5 billion in 2012.

近来，由于生物仪器和激光投影领域的强烈需求，紧凑高效的RGB（红、绿色、蓝）激光器已经引起了广泛关注。生物技术仪器市场的快速增长正在创造意想不到的应用，如DNA和细胞分析。根据Laser Focus World，2006的市场预测，2007年用于生物仪器应用的激光器市场估计将超过4.7亿美元。据估计，这些应用的激光器市场在2012年将达到约10亿美元。在激光投影领域中，需要具有从几毫瓦到几瓦的输出功率的紧凑的红、绿色、蓝（RGB）激光器。然而，由于缺乏合适的材料，绿色半导体激光二极管（LD）不可用，并且来自可用蓝色LD的输出功率不足，并且来自可用红色LD的光束形状对于激光投影不够好。据Insight Media预测，2012年激光显示器市场总额将达到25亿美元。
