2015 Taylor & Francis. Currently, no light source exists which is both narrowband and speckle free with sufficient brightness for full-field imaging applications. Light-emitting diodes are excellent spatially incoherent sources, but are tens of nanometers broad. Lasers, on the other hand, can produce very narrow-band light, but suffer from high spatial coherence which leads to speckle patterns, which distort the image. Here, we propose the use of random Raman laser emission as a new kind of light source capable of providing short-pulsed narrow-band speckle-free illumination for imaging applications.
