Lasers possess many attractive features (eg, high brightness, narrow linewidth, well-defined
polarization) that make them the ideal illumination source for many different scientific and …

A broadband green light source was demonstrated using a tandem-poled lithium niobate
(TPLN) crystal. The measured wavelength and temperature bandwidth were 6.5 nm and …

A dynamic light scattering liquid crystal (DLS-LC) device is applied to reduce speckle from a
laser pico-projector. The DLS-LC device produces time-varying scattering patterns, which …

The artefact known as speckle can plague numerous imaging applications where the narrow
linewidth of laser light is required, which includes laser projection and medical imaging …

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 …

High coherence in laser light causes spatially distributed interference called speckle. In
applications such as holographic projection, this undesirable side effect degrades image …

ABSTRACT A liquid crystal (LC) with negative dielectric anisotropy called N-(4-
Methoxybenzylidene)-4-Butylaniline (MBBA) doped with the ionic agent …

Miniaturized and pure static devices are expected to be used in laser-imaging systems for
speckle reduction. In this study, a pure static device based on polymer-stabilized liquid …

We propose a system that reduces laser display speckles by vibrating the light pipe. A small
displacement of the light pipe appears to allow the total reflection of the laser, thereby …

We propose a robust method to suppress laser speckle using a polymer-stabilized liquid
crystal (PSLC) device with high initial transmittance. With applied voltage, a large …
