ENGINERED BY LASER QUANTUM

FINESSE CONTINUOUS WAVE LASER SERIESULTRA LOW NOISE AND HIGH SPECIFICATIONLASERS
Novanta develops photonics solutions specializing in
cutting-edge components and sub-systems for laserbased diagnostic, analytical, micromachining andfine material processing applications. Powerful lasers,
coupled with advanced beam steering and intelligent
sub-systems incorporating software and controls, deliver
extreme precision and performance, tailored to ourcustomers’ demanding applications.

DESIGNED FOR SPECIFICATION

Optical noise (%RMS)

Optical power (mW)The finesse range of lasers offer top of the range
performance at a high-power output of up to 16W. A
novel cavity design and clever integrated electronics
deliver exceptional power stability and ultra-low noise
making this product ideal for the highly demanding Ti:Spumping applications whilst ensuring consistent andrepeatable results for the Semiconductor inspectionindustry. Unique features in the form of CEP stabilization
makes the finesse a perfect fit for Carrier Envelope Phaselocking applications.
Fig. 1 Typical power
and noise stability ofthe finesse pure laser.
Power stability (blue)<0.05 % and the noise(red) ~0.01 % shownover a 70 hour period.

Fig. 2 finesse pure CEP
removes the need for
an AOM, offering simpler setup design andlower integrated CEPphase noise.

The finesse laser uses pure™ technology producing <0.02 % noise

UNIQUE FEATURES
Exceptional power stability and ultralow noise ensure
consistent and accurate results.
•Novel cavity design fundamentally enabling
exceptionally stable power output.
•Noise cancellation electronics actively work to deliver
ultralow noise.
High power and exceptional wall plug efficiency
enables applications.
•Up to 16W of continuous wave 532nm delivers highpower on sample/target•
Exceptional wall plug efficiency results in low heatdissipation and reduces thermal management
requirements
Reduce cost and complexity.
•CEP feedback loop allows for direct modulation ofoutput using f2f interferometer signal; removing costand complexity from system design

Field Replacements: The finesse range benefits
from pump diodes situated in the intelligent power
controller to facilitate heat management and allows
field replacement.

•CEPLoQTM Technology: directly modulates
the pump power to maintain phase stabilisation
without the use of an AOM; faster and more stable
responses than the traditional method.

•Intelligent control unit: Allows easy settingand monitoring of the laser parameters.
Incorporating PowerLoQ™ technology, the gem
lasers show extreme power stability over longperiods of use.

•1200 g drop-test: (Fig. 2) All gem lasers undergoa drop test to check that all components arecorrectly fitted prior to its extended 300 hour
test period. This rigorous testing regime ensureslong operational lifetimes.

•RemoteAppTM: Works with software thatallows the laser to be controlled locally, overthe internet and connected directly to oursupport team for monitoring laser performance,
