Laser tube
f201 lasers were developed using new technology patented by NOVANTA. F201 laser’s patented “f”
technology, based on an unstable free-space resonator design, enables NOVANTA to economically pro-
duce a symmetrical laser beam from a small but powerful laser capable of operating for many years with
virtually no maintenance. F201 laser’s unique extruded aluminum envelope offers excellent heat transfer,
long gas life, and low operating costs in contrast to other laser tube technologies. Besides being the vessel
that maintains the lasing environment, the aluminum tube is also the structural platform that integrates
the laser’s optical, electrical, and cooling components.
Duo-Lase’ operation
F201 laser lasers consist of two standard, sealed tubes (f201 tubes respectively) that are combined using
NOVANTA’s Duo-Lase
®
technology to provide a single diffraction-limited beam at twice the output power.
All power and control functions between the two laser sections are totally independent, essentially
achieving fail-safe operation for applications that can be served with the power of a single laser tube. Any
one electronic or laser tube failure will affect only that section, leaving the second section unaffected and
available for temporary use.
The Duo-Lase optical combining technique is based on the fact that each tube is linearly polarized, which
allows the use of a polarization-sensitive beam combiner to achieve a 98 percent efficiency in combining
the two beams. Both components of the resulting output beam are spatially parallel and collinear. The
normal temporal and spatial variations inherent in a single tube laser are reduced by combining the output
of two lasers.
