Patent ·
OSTI ID:6520837
This patent describes a laser apparatus comprising: means including a laser medium capable of emitting a beam of coherent laser energy having both lower order and higher order modes; means for reflecting at least a portion of the energy in the beam back through the lasing medium; and means including a laser energy transmissive optical element for discriminating against the higher order modes by non-linearly amplifying the reflected beam portion passing through the lasing medium.
