OEM v30 laser
Laser Tube
OEM v30 lasers were developed using new technology patented by NOVANTA, Inc. This patented “v”
technology, based on a combination of free-space and waveguide resonator designs, enables NOVANTA
to economically produce a symmetrical laser beam from a small but powerful laser capable of operating
for many years with no maintenance. Firestar’s unique extruded aluminum envelope offers excellent heat
transfer, long gas life, and low operating costs in contrast to other laser tube technologies. In addition to
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.
Optical resonator
The optical resonator, in conjunction with the electrodes and the gas mixture, generates the laser beam.
v30 optical resonators are comprised of four optical elements: a rear mirror, two turning mirrors, and an
output window. These optical elements are fastened to the tube’s exterior and are exposed to its interior
through holes in the end caps. O-rings sandwiched between optical elements and each end cap form a
