Different applications and results in the generation of laser-induced negative ions are reviewed. Emphasis is put on analytical achievements as well as recent developments in very high negative ion currents. Yields up to 4 mA have been observed. The production mechanism is discussed. Three-body collisions in the extremely dense laser plasma are considered to be the origin of the strong yields observed. Already, a dedicated source has been constructed, but, e.g., a conventional cesium-beam sputter source is also well suited to serve as a laser ion source.
