摘要：
A light source having (a) a light emitter that emits a light beam along a first axis, the light beam having a highest degree of anisotropic coherency in a second axis perpendicular to the first axis; and (b) a light multiplexer positioned optically downstream of the light emitter, the multiplexer having an axis of multiplexing perpendicular to the first axis, the second axis and the axis of multiplexing being oriented at an angle with respect to each other that is other than 0, 90, 180 and 270 degrees.
