Intracavity frequency-doubled degenerate laser

Seng Fatt Liew, Sebastian Knitter, Sascha Weiler +5

We develop a green light source with low spatial coherence via intracavity frequency doubling of a solid-state degenerate laser. The second harmonic emission supports many more tra…

Coherence switching of a degenerate VECSEL for multimodality imaging

Sebastian Knitter, Changgeng Liu, Brandon Redding +3

We demonstrate a VECSEL (vertical external cavity surface emitting laser) based degenerate source with an adjustable degree of spatial coherence that is electrically pumped, mechan…

Low-spatial-coherence broadband fiber source for speckle free imaging

Brandon Redding, Peyman Ahmadi, Vadim Mokan +3

We designed and demonstrate a fiber-based amplified spontaneous emission (ASE) source with low spatial coherence, low temporal coherence, and high power per mode. ASE is produced b…

Low-spatial coherence electrically-pumped semiconductor laser for speckle-free full-field imaging

B. Redding, A. Cerjan, X. Huang +4

The spatial coherence of laser sources has limited their application to parallel imaging and projection due to coherent artifacts, such as speckle. In contrast, traditional incoher…

Speckle-free laser imaging

Brandon Redding, Michael A. Choma, Hui Cao

Many imaging applications require increasingly bright illumination sources, motivating the replacement of conventional thermal light sources with light emitting diodes (LEDs), supe…

Spatial coherence of random laser emission

Brandon Redding, Michael A. Choma, Hui Cao

We experimentally studied the spatial coherence of random laser emission from dye solutions containing nanoparticles. The spatial coherence, measured in a double-slit experiment, v…
