Is it possible to form an image using light produced by stimulated emission? Here we study light scatter off an assembly of excited chromophores. Due to the Optical Theorem, stimulated emission is necessarily accompanied by excited state Rayleigh scattering. Both processes can be used to form images, though they have different dependencies on scattering direction, wavelength and chromophore configuration. Our results suggest several new approaches to optical imaging using fluorophore excited states.
利用受激辐射产生的光能否形成图像？在这里，我们研究了光从一组激发态发色团散射的情况。由于光学定理，受激辐射必然伴随着受激态瑞利散射。这两个过程都可以用来形成图像，尽管它们对散射方向、波长和发色团结构的依赖性不同。我们的结果为利用荧光团激发态进行光学成像提出了几种新方法。
