… frequency diversity of speckle. Having limited ourselves to the topic of frequency diversity and
… (16) we calculate the following wavelength spacings as adequate to correlate speckle (see …

… The linewidth of each laser is about 0.1 nm, which is small enough not to have speckle
reduction effect by wavelength diversity in our experiment. The emitted light from the fiber entered …

… We have used a multimode fiber optic bundle for speckle reduction in a laser illumination
system. Beams from two independent lasers of same wavelength and power are combined, …

… The speckle reduction by the wavelength diversity of the lasers was also studied. Both
broadband lasers and narrowband laser were used for experiment. It is experimentally shown …
