Ultrashort laser pulse generation
... In the stationary state, the SAM effect leads to a net loss before and after the pulse, preventing satellite pulses or some lowintensity background from emerging. With a broad-band gain and low GDD, it could, in principle, shorten the pulse down to the sub-100-fs regime. However, SAM induced by a sa ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
