ENGINEERED BY LASER QUANTUM

TORUS DPSS CONTINUOUS WAVE LASER SERIESACTIVE MODE LOCKING, SINGLELONGITUDINAL MODE LASER
Novanta develops photonics solutions specializing in cutting-edge
components and sub-systems for laser-based diagnostic, analytical,
micromachining and fine material processing applications. Powerfullasers, coupled with advanced beam steering and intelligent
sub-systems incorporating software and controls, deliver extreme
precision and performance, tailored to our customers’ demanding
applications.

LEADING LIFETIMES
Based on an ingenious virtual ring cavity design the torus family of
single longitudinal mode lasers stands out for its unique spectral
characteristics. A bandwidth of <1MHz and market leading spectral
purity makes this laser ideal for demanding applications including
Brillouin Scattering, Raman Spectroscopy, Interferometry andHolographic applications.

The torus laser with active mode-locking

Advanced design characteristics include active mode locking, atechnology that minimizes mode drift, eliminates mode hope andgenerates an ultra-stable spectral output.

• TruLoQTM: Effects of temperature change on the laser such as
mode-drift and mode-hop are minimized.
• 1200 g drop-test: (Fig. 2) All gem lasers undergo a drop test
to check that all components are correctly fitted prior to its
extended 300 hour test period. This rigorous testing regime
ensures long operational lifetimes.
• RemoteAppTM: Works with software that allows the laser to becontrolled locally, over the internet and connected directly to
our support team for monitoring laser performance, diagnosing
opportunities and carrying out laser optimization.
