带边液晶激光器对于包括激光投影显示器在内的许多应用是令人感兴趣的。在这里，我们展示了同时红-绿-蓝激光从一个单一的液晶样品，通过创建一个二维激光器阵列制造的染料掺杂的手性双折射液晶。通过在整个单元上形成间距梯度，并使用小透镜阵列光学泵浦样品，可以观察到同时由红-绿-蓝颜色组成的多色激光阵列。具体地，二维多色阵列可以用于产生具有低散斑和宽色域的基于激光的显示器，由此不需要复杂的制造过程来生成各个“像素”。(C)2008年美国光学学会
Band-edge liquid crystal lasers are of interest for a number of applications including laser projection displays. Herein, we demonstrate simultaneous red-green-blue lasing from a single liquid crystal sample by creating a two-dimensional laser array fabricated from dye-doped chiral nematic liquid crystals. By forming a pitch gradient across the cell, and optically pumping the sample using a lenslet array, a polychromatic laser array can be observed consisting simultaneously of red-green-blue colors. Specifically, the two-dimensional polychromatic array could be used to produce a laser-based display, with low speckle and wide color gamut, whereby no complex fabrication procedure is required to generate the individual 'pixels'.
