…its central emission frequency with high
precision by adjusting the NPRO crystal temperature or
by fine tuning it with a fast integrated piezo transducer (PZT). It allows the user to have full control
over the laser emission - which is extremely important in atom cooling and trapping…

COHR WP OPSL No Green Noise final 5.15.18.pdf

…requires active thermal stabilization of the cavity as well as the
ability to lock the cavity length and etalon performance together using piezo mirror mounts and
feedback electronics. This all adds cost and complexity.
Some commercial low-noise DPSS lasers are based on other active…

…single-mode output is then connected to
the single-mode illumination-delivery
fiber in the SFE. At the distal end of the
endoscope, a piezo tube actuator deflects
a scanning fiber across the field of view.
Why three wavelengths? The 640-nm
channel will be used for an…

…this control also
provides the ability to tune the absolute frequency of
Mephisto.
Fast and fine control is achieved by use of a piezo
electric transducer (PZT) element attached to one of
the large non-optical facets of the crystal. (i.e., one of
the horizontal surfaces…

…noise starting level of the Mephisto
laser. Fortunately for LIGO, the Mephisto already contains frequency control elements in
the form of piezo (fast) and temperature (slow) adjustments of the monolithic laser cavity.
These can be used to reduce the frequency noise by stabilizing the…
