GIGAOPTICS' femtosecond oscillators
GIGAJET 20, 20c and 30s are available
as TWIN Version. Any two of the three models can be combined on a single
monolithic platform to form a TWIN version. Repetition
rate fluctuations of the free-running lasers are highly synchronous. Thus,
if required, active stabilization of the lasers at equal repetition rates
or at fixed detuning is straightforward and easy. Protected by U.S. patent 6,618,423 and European patents.
The TWIN version of the GIGAJET
oscillators is used for applications where two femtosecond lasers with high absolute and relative
repetition rate stability are required. The two lasers can be stabilized at equal repetition rates
or with fixed repetition rate detuning using our products TL-1000 and
TL-1000-ASOPS.
Aside from applications at equal repetition rates, e.g. two-color pump-probe spectroscopy,
novel spectroscopy techniques where the repetition rates have a fixed detuning are especially
interesting. Such applications that are very efficiently realized with Gigahertz repetition
rates are high-speed asynchronous optical sampling
[A. Bartels et al., Rev. Sci. Instrum. 78, 035107 (2007)] or time-domain FTIR spectroscopy [F. Keilmann et al., Opt. Lett. 29, 1542 (2004).].

Researchers at University of
Konstanz have demonstrated a THz spectrometer with an unprecedented 142 MHz frequency precision.
The rapid-scanning system is based on high-speed ASOPS and uses a
GIGAJET TWIN dual femtosecond oscillator.
