ABSTRACT:
A laser apparatus for providing a stabilized multi mode laser beam includes an external cavity for providing an optical path for generating a laser beam which is stimulated by a gain medium, where the external cavity has first spectral characteristics, and a mode-selecting filter positioned within the optical path and having second spectral characteristics. The first characteristics and the second characteristics are adjusted to each other, so that the laser beam has at least two selected modes.
