摘要： An image displaying apparatus includes laser light sources corresponding to a plurality of colors, while at least one of the laser light sources corresponding to one of the colors includes a plurality of wavelength conversion laser light sources corresponding to a mutually same color and has a plurality of outputs. The image displaying apparatus is operable to display a color image by causing a spatial modulation element to perform a spatial modulation process on laser beams output from the laser light sources by using a field sequential method. When the spatial modulation element performs the spatial modulation process on the laser beams output from one of the laser light sources (e.g., the green laser light source) having a plurality of outputs, a drive controlling device causes green laser emitting units serving as the wavelength conversion laser light sources to sequentially output pulses so that the laser beams output from the green laser emitting units continuously form substantially constant laser outputs that have substantially the same peak power as each other.

摘要： A coherent light source includes a plurality of light emitting points arranged in one-dimensional array.

A magnification of a focusing optical system is set such that a light emitted from the beam shaping unit is coupled to an optical fiber based on a maximum diameter of the light emitted from the beam shaping unit.
