Ultrafast Lasers / Graduate Texts in Physics (PDF)

Ursula Keller, a tenured professor of physics at ETH Zurich since 1993, leads the Ultrafast Laser Physics group, and currently also serves as a director of the Swiss multi-institute NCCR MUST excellence program in ultrafast science since 2010. Born 1959 in Zug, Switzerland, she received the Physics "Diplom" from ETH Zurich in 1984 and the Ph.D. in Applied Physics from Stanford University, USA in 1989. She was a Member of Technical Staff (MTS) at AT&T Bell Laboratories in New Jersey from 1989 to 1993. She was a "Visiting Miller Professor" at UC Berkeley in 2006 and a visiting professor at the Lund Institute of Technologies in 2001. She has been a co-founder and board member for Time-Bandwidth Products since 1995 and for GigaTera from 2000 to 2003, a venture capital funded telecom company during the "bubble phase" which was acquired by Time-Bandwidth in 2003. Time-Bandwidth Products was acquired by JDSU in 2014. Her research interests are exploring and pushing the frontiers in ultrafast science and technology. She invented the semiconductor saturable absorber mirror (SESAM) which enabled passive modelocking of diode-pumped solid-state lasers and established ultrafast solid-state lasers for science and industrial applications. She pushed the frontier of few-cycle pulse generation and full electric field control at petahertz frequencies. Pioneered frequency comb stabilization from modelocked lasers, which was also noted by the Nobel committee for Physics in 2005. In time-resolved attosecond metrology she invented the attoclock which measured the electron tunneling delay time and observed the dynamical Franz-Keldysh effect in condensed matter for the first time.
