A spherical laser includes a transparent or semi-transparent outer spherical vessel having an internal cavity, an amplifying medium in the cavity, and means to excite the amplifying medium. The sphere is provided with a partially reflective coating to act as a spherical optical resonator. The spherical resonator includes a plurality of optically different regions containing alternative optical media from the cavity medium differing in bulk optical parameters utilized for mode tailoring. The optically different regions work collectively to exclude the whispering gallery modes from those supported by the spherical cavity. Excitation of the amplifying medium produces an optical gain. When the gain exceeds cavity losses and threshold conditions are met, lasing is supported. This creates a three-dimensional, spherically radiating emission, emulating a point source. The sphere is enclosed within a mirrored ellipse to image the output to a point, or within a mirrored parabola to columinate the emission.
