Example: All Normal Dispersion (ANDi) Laser

*All of the following discussion is from Chin Yu (Andy) Chong’s thesis on this laser. The citation for this is: Chong, Chin Yu. “Femtosecond fiber lasers and amplifiers based on the pulse propagation at normal dispersion.” (2008).

The all normal dispersion, or ANDi, laser is an ultrafast fiber laser that is based entirely on normal dispersion i.e. $\lambda \leq 1.3 \mu{m}$ for silica host media, as the same suggests. This is a novel design, because typically for ultrafast fiber lasers, both a normal and an anomalous dispersive segment are needed such that the dispersion can be compensated in the laser. To solve this, the ANDi laser uses a spectral shaping component.
