…(M2 <1.2) result
in superior performance in any application where
beam profile is critical, like pumping collinear OPAs and
NOPAs or for fine material modification studies.
An integrated AOM allow to change the repetition

…controlled non-linear
processes as planned with the HCF. Moreover, this amplifier had been configured for ~120 fs
pulse width for NOPA pumping. NOPAs are ideally driven with long pulses that are easy to
generate. The HCF approach is generally driven by short pulses. Hence there is…

…amplifier (a 6-W
Coherent Astrella), which the researchers
use to pump a home-built, noncollinear optical parametric amplifier (NOPA) where
the center wavelength can be tuned for different experiments.
Fleming explained the choice of laser
amplifier: "In four-wave…
