The high efficiency and high power semiconductor laser with multi-active regions which are cascaded by reverse biased tunnel junction has a higher inner quantum efficiency which can larger than 1, so that it can output higher optical power at the same injected current compared with the normal lasers, meanwhile, it can be designed to large coupled optical cavity, so it will increase the limit of the electro-thermal destroy and the COD.

通过反向偏置隧道结将多个有源区级联起来的多有源区耦合大光腔高效大功率半导体激光器从理论上解决了传统激光器存在的问题，由于其内量子效率大于1，可以在相同电流下输出高的光功率，且可以制成耦合大光腔结构，增大了光腔面积，因此相对于传统激光器而言，其电热烧毁和COD水平都会提高。

Second, in this paper we recite and analyse how the painting masters of the different history stage used light and colors from "Prehistorical art" to "Rome art" imitating light and colors,"Middle ages art" creating "Sanctitude light","Revival of learning" representing nature light and colors and then light was used to create the drama light, Impressionistic using the light of science and impairing light instead emphasizing sensibility colors in modern times. Painting lives by the light and colors all along in the painting history.

从史前艺术、希腊罗马艺术的模仿光与色，到中世纪艺术创造神圣之光，再到文艺复兴的再现自然光线与色彩，然后到17世纪的主观处理光线形成"戏剧之光"、印象派的科学用光、现代绘画淡化光线并强调情感色彩，光线和色彩一直贯穿在历史的绘画长河里。

Modern Chinese artists from China's stage arts, folk art and modern Western painting and drawing useful, a point-kwong, presented by the color tone sandhi a level, the changes in light, to break through the traditional flat light, and that this light A screen Smart lively language.
