Self-referenced frequency combs bridge optical to radio frequencies by a
phase-stable link and thereby triggered significant progress in areas such as
precision metrology and spectroscopy. The breakthrough was possible by measurement and stabilization of the carrier-envelope offset
(CEO) frequency signal. This signal represents the otherwise unknown offset of
the comb and enables absolute knowledge on the frequencies of its optical
spectrum. This thesis describes the development of compact ultrafast laser
oscillators and their efficient spectral broadening in highly nonlinear fibers for the generation of self-referenced frequency
combs. Diode-pumped solid-state lasers (DPSSLs) are a promising alternative to
overcome many limitations of current Ti:sapphire
or fiber laser systems. We report on the first
measurement and stabilization of the CEO frequency signal from a DPSSL
operating in the 1.5 μm spectral region. The laser uses a high-Q cavity, which consumes less
than 1.5 W of electrical power and results in low-noise operation. We generated
the necessary coherent octave-spanning supercontinuum directly from the laser
output without amplification or compression. This key challenge is solved by
implementing a novel polarization maintaining highly nonlinear fiber. A free-running linewidth of only 3.6 kHz is
achieved, which is an improvement of more than an order of magnitude when
compared to femtosecond fiber laser systems operating
in this spectral region. The CEO frequency is controlled and stabilized by the
pump current, proving the development of an exciting tool for future usage in
frequency metrology applications. Moreover, these results will open the door to
novel optical frequency combs from diode-pumped solid-state and semiconductor
lasers, which is a particularly important step towards scaling of the
repetition rate.
Max C. Stumpf received his diploma in physics from the Friedrich-Schiller-University
in Jena, Germany 2005. He joined the Institute for Quantum Electronics at ETH
Zurich, Switzerland 2006. His research interests include the development of
novel ultrafast laser sources, in particular low-noise diode-pumped solid-state
lasers, high brightness fiber sources, supercontinuum
generation, as well as optical frequency metrology.
