利用由平凸微透镜组成的小透镜阵列对单个液晶样品进行了泵浦，实现了二维液晶激光器阵列。已经产生了由1 mm非活性区域间隔开的LC激光器的5 x 5阵列（显示相互相干的证据），其可以组合以产生单个单模输出，并且与单焦点LC腔相比，允许能量密度增加近50倍。此外，我们已经证明了如何个人和重组的发射光谱不同的样品拓扑结构和多域样品可以用来产生多波长的激光发射。(c)2008年美国光学学会。
A two-dimensional liquid crystal (LC) laser array has been demonstrated by photopumping a single LC sample using a lenslet array consisting of plano-convex microlenses. A 5 x 5 array of LC lasers (displaying evidence of mutual coherence) spaced by 1 mm inactive regions has been generated, which could be combined to yield a single monomode output and allows an almost 50-fold increase in energy density in comparison to a single-focus LC cavity. Furthermore, we have demonstrated how the individual and recombined emission spectra vary with different sample topologies and how polydomain samples can be used to generate a multiwavelength laser emission.
