TLB-6900 Vortex™ II Tunable Lasers HIGHEST FREQUENCY STABILITY AVAILABLE Introducing the New Focus™ Vortex II laser for precision applications. When frequency stability is the key to the success of your experiment, turn to the Vortex II for the confident knowledge that you have the epitome of tunable single mode laser design. We have taken three generations of our award winning laser engineering, space qualification, and OEM experience and added Star-Flex motion actuation and patent-pending magnetic damping. The result is a laser whose frequency stability is unsurpassed. Mechanical resonances have been reduced so whether you are running open loop or frequency locking the Vortex II you will obtain the highest quality results available.

TLB-6900 Vortex™ II Tunable Lasers Star-Flex is a motion actuation design like no other. Nanometer scale positional errors translate to unacceptable mode hops and wavelength jitter and drift. Strict rotational motion (without translation) about the tuning pivot point is crucial to mode hop-free tuning. But this is difficult to achieve in combination with low susceptibility to vibrational perturbations. Thermal and finite element analyses led us to the Star-Flex design that provides stiff, reproducible rotational motion without any translation. Further reduction in jitter is accomplished with...
