Tunable Diode LasersThe Philosophy of New Focus LasersNew Focus lasers are designed to be complete and easy-to-use systems.Complete SystemsNew Focus laser systems are plug-and-play, fully-functioningsystems which include active current drive and closed looptemperature control.TLB-7100 Vantage Laser and TLB-6800-LN Controller.Laser Head RecognitionSafety FeaturesFor systems with modular laser heads and controllers,critical diode settings, mximum current and optimumtemperature are stored in the laser head. These criticalparameters are determined and set at the factory during thebuild of each individual laser unit. The correspondingcontroller calls this information from the laser head onstartup ensuring top performance.The critical settings stored in the laser head prevent fataldamage to the tunable laser system, particularly to the laserdiode or tapered amplifier chip. The preset maximumcurrent value prevents the user from delivering too muchcurrent. Each tapered amplifier has a safety shutoff featurethat is enabled when the seed drops below a safe power.DesignOver the decades, New Focus has accumulated vast ECDL engineering and production know-how. This knowledge shows inour design. Mechanical design, including Star-FlexTM actuation and magnetic damping reduce vibrational noise. Heavy housing and thermal insulation for temperature and acoustic isolation. Low noise control electronics for narrower linewidths.What is Magnetic Damping?The New Focus Velocity, Vortex Plus, and Vantage Lasers incorporate patent pending magnetic damping to improve laserstability. External vibrations coupled into the laser cavity can excite the natural mechanical frequencies of the laser tuningarm. A magnet is placed behind the tuning arm to dampen the amplitude of these unwanted vibrations that lead to laserfrequency instability and linewidth broadening.P h o n e : 1 - 8 7 7 - 8 3 5 - 9 6 2 0 w w w. n e w p o r t . c o m / N e w F o c u s5

The 6700 Controller monitors the Velocity laserscurrent, temperature, and wavelength. Each head hasoptimized factory settings. The 6700 Controller will read thelaser's optimum settings and automatically limit the currentand scan ranges to protect the laser diode cavity. Operationis simple: either from the front panel or via the USB GUI, theuser can just dial up and set the desired wavelength andpower. Minimum and maximum wavelengths points can beentered, and the Velocity can be set to scan back and forthbetween them.

Strontium is one of nature’shighest-Q frequency references, with a quality factor of 1018.This clock takes advantage of the lower quantum projectionnoise of a many-body quantum system to achieve newrecords in clock precision, stability, and total systematicuncertainty. To prepare the atoms for precisionspectroscopy, they are first laser-cooled using light from 461nm blue diode lasers. Then, after a second red laser coolingstage, the atoms are loaded into an optical lattice, wherethey are trapped in standing waves of light. The clock laseris then used to perform coherent spectroscopy. The bluelight is used again to measure the number of atoms in theground and excited states via fluorescence. This allows us tomeasure the laser frequency against the atomic resonance.Strontium Optical Lattice - Courtosy ofProf. Jun Ye, UC Boulder, JILA, NISTP h o n e : 1 - 8 7 7 - 8 3 5 - 9 6 2 0 w w w. n e w p o r t . c o m / N e w F o c u s

Tunable Diode Lasers13Precision Tunable Laser Evolution of Excellence1996Introduced in 1996 the Vortex 6000Series Tunable Lasers offered narrowlinewidth and low-noise performancebuilt to our customer’s wavelengthspecifications. Based on a provenmonolithic design, there were noadjustable components that couldbecome misaligned over time. Thelaser cavity and drive electronics weredesigned to provide maximumfrequency-modulation capabilities,allowing for modulation above thefrequencyofmechanical-noisesources.2004Vortex Stablewave 2008Vortex IIThe New Focus engineering team wasonce again asked to provide the nextlevel of laser performance that wouldhelp the atomic spectroscopycommunity and others by providinglow frequency jitter and low driftmode-hop-free tunable laser. TheVortex II 6900 Series, the thirdgeneration fine tuning ECDL designreleased in 2008, was even moreresistant to acoustical and mechanicalperturbations than its predecessor.The technical challenge came down tostiff rotational motion withouttranslation. It was under this mandatethat Star-Flex motion actuation andthe patented technique of magneticdamping were born.In 2002, New Focus partnered withNASA’s Jet Propulsion Laboratory(Pasadena, CA) to develop the nextgeneration atomic clocks formicrogravity measurements andGPS space deployment, as part of anexperiment to test many of thepredictions of Albert Einstein’sTheory of Relativity. New Focusproudly released the Stablewave7000 Series in 2004. To deliver trulyreliable performance, these lasersused an exceptionally rugged,patented laser cavity.2012Vortex PlusThe Vortex Plus is the latest addition to the New Focus lineof Finely Tunable Littman-Metcalf Lasers. Conserving thesame robust cavity and StarFlex actuator, New Focus hasadapted the Vortex II to accept longer diode chips, resultingin significantly higher output power. The Vortex Plusoperates with our low noise TLB-6800-LN laser controller,reducing the laser linewidth from 300 kHz to 200 kHz. Also,an SMA port for direct diode current modulation has beenreintroduced to the Vortex Plus, enabling up to 100 MHz highspeed modulation.P h o n e : 1 - 8 7 7 - 8 3 5 - 9 6 2 0 w w w. n e w p o r t . c o m / N e w F o c u s

The Vortex II has improved stability due to the Star-Flex design andmagnetic damping.The Star-Flex design was engineered to be robust enough towithstand a space shuttle launch environment and operatefor years in space. The design had to pass strict tests to meetthe requirments for space readiness.

The controller allows you to easily fine tune and adjust the output power or bias currentwith the press of a button or, via the USB/RS-232, interface with the click of a mouse. There is no need for an external functiongenerator to drive the piezo of your tunable laser with the built in function generator.
