Abstract:
1. A laser system comprising: a laser light source operable to output illuminating light; a display device operable to receive the illuminating light; an optical fiber operable directed the illuminating light from the laser light source to the display device, wherein the optical fiber has a core extending along a central longitudinal axis and a cladding layer covering the core, the core having a refractive index profile defined from the central longitudinal axis to a longitudinal edge, the refractive index profile comprising a first refractive index at the longitudinal edge that is greater than a second refractive index at the central longitudinal axis; and a vibration device attached to the optical fiber, wherein the vibration device is operable to vibrate at a frequency greater than a threshold frequency so as to reduce speckle.
