Synopsis by Lori Moore
... This gives a high frequency cutoff for NIF of about 120 λ. For their application the scattered intensity is diffracted out of the main laser beam or can be adequately controlled using a spatial filter. For other applications the PSD of this region may be more critical to the performance. One example ...

With standard optical fiber, at 1550 nm, a chirp-less source is required to achieve bit rates higher than 10 Gb/s. It is expected that fast and chirp-less modulation could be ...
