Patent attributes
The invention relates to a saturable absorber mirror comprised ofa) 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, andd) 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).
