Coherent light, as produced by lasers, is much more intense and bright
than non-coherent light. However, unlike non-coherent light sources
coherent light from a laser does not radiate away from its source in a
spherical fashion, but instead travels in a substantially straight path
directly away from the source in a unidirectional beam. Direct exposure
to coherent light is potentially dangerous to the human eye and consumer
products employing laser-light sources are carefully regulated.
Consequently, as a result of the radiation characteristics of coherent
light, coherent light sources have not previously been employed for use
in a signaling wand or any other direct-lighting apparatus. In contrast
to the prior art, embodiments of the present invention provides an
apparatus for emitting intense non-coherent light derived from a coherent
light source (e.g. laser).
