Understanding the dynamics of complex processes requires fast optical imaging. Although laser pulses can have high brightness, their inherent high coherence degrades the image quality due to speckle formation. A random laser is an atypical laser technology in which scattering particles provide optical feedback. It can be engineered to provide low spatial coherence to perform speckle-free full-field imaging. In this chapter, we first study the operation principles and characteristics of random lasers. Then, we explain how the unique characteristics of random lasers allow them to be used as new imaging light sources with unprecedented brightness, delivering speckle-free and narrow-band light. We illustrate the advantages of random laser imaging in studying the dynamics of cavitation formation in liquids with different experimental setups.
