The random raman laser: A new light source for the microcosmos

In modern microscope imaging techniques, lasers are used as light sources because they can deliver fast pulsed and extremely high-intensity radiation to a target, allowing for rapid image acquisition. However, traditional lasers come with a significant disadvantage in that they produce images with blurred speckle patterns -- a visual artifact that arises because of a property of traditional lasers called "high spatial coherence." These speckles greatly reduce image quality in wide-field microsco...
