| Zusammenfassung: | The invention relates to a saturable absorber mirror comprised of a) a rear-side reflector layer (2), b) an intermediate layer (6), the boundary areas of which form an interference filter, c) at least one absorber layer arranged within the interference filter and comprised of a material absorbing a light at operating wavelength of the saturable absorber mirror depending on intensity, and d) a front-side cover layer, it is the object of the invention to provide a saturable absorber mirror having improved properties. To this effect the invention proposes that the interference filter is neither resonant nor anti-resonant at operating wavelength, with the intensity (I) of the electromagnetic stationary wave field of the light in the interior of the cover layer (5) having a local extremum (8). |
