Ultrashort pulse lasers are important tools in time and frequency
metrology, atomic spectroscopy, and medical applications. Passively
modelocked fiber lasers are short pulse lasers that have many advantages
over non-fiber alternatives --- particularly size, weight, and cost.
However, fiber lasers can drift due to environmental changes and changes in
fiber properties, making robustness a problem. Although fiber modelocked
lasers have been studied for decades, until recently modeling these devices
has primarily been phenomenological. In this talk, I will discuss how
passively modelocked fiber lasers work, improvements in the modeling effort
in recent years, challenges for their robustness, and possible improvements
for robustness based on our modeling work.

Brian Marks is a research scientist in the computational photonics
laboratory at UMBC. He received his Ph.D. in Engineering Sciences and
Applied Mathematics at Northwestern University, and B.S.'s in Math and
Physics from N. C. State University. He was at UMBC from 2000--2005 in the
computational photonics lab, then taught math and statistics at Indiana
University in Bloomington for several years, and is now back at UMBC. His
research interests include modeling and simulation of photonics and
communications systems.
