Abstract:
1. An optical oscillator system, comprising: an end mirror and an output coupler defining a resonator cavity for an intracavity beam and producing an output beam with selected spectral components; a gain medium positioned in the resonator cavity; an aperture member positioned in the resonator cavity in a path of the intracavity beam, the aperture member defining an aperture that provides a low loss intracavity beam path for a range of spectral components; a dispersion member with first and second sides and positioned in the resonator cavity, wherein when the intracavity beam travels from the first side to the second side along a path, the dispersion member creates a spatial spread of the range of spectral components, and when the intracavity beam travels from the second side to the first side along the path the process is reversed; and a movably mounted mirror, wherein in response to a feedback signal the movably mounted mirror moves to maintain the output beam at a same position at the output coupler, wherein the movably mounted mirror is positioned between the aperture member and the end mirror.
