Abstract
A light detection and ranging (LIDAR) apparatus is provided that includes an optical source to emit an optical beam towards a target and a mode field expander operatively coupled to the optical source to expand a mode area of the optical beam from a first mode of a single mode optical fiber to a second mode of a larger mode area optical fiber.
