The New Focus™ tunable external cavity diode lasers deliver true continuous mode-hop-free tuning. The Vortex™ Plus TLB-6800 is our highest performance precision finely tunable external cavity diode laser. The Littman-Metcalf cavity configuration provides exceptional stability, piezo mode-hop-free tuning range and narrow linewidth. The Vortex Plus uses Star-Flex™, a motion actuation design like no other. Thermal and finite element analyses led us to the Star-Flex design that provides stiff, reproducible rotational motion without any translation.

Features
High Stability, Narrow Linewidth
High stability is provided by the Star-Flex tuning arm actuator design. The design provides stiff, reproducible rotational motion without any translation. In addition, precise temperature control of the laser cavity and diode allow us to reduce wavelength drift and power fluctuations. We have incorporated our unique magnetic dampening to minimize frequency jitter and drift. The accompanying TLB-6800-LN Tunable Laser Controller delivers high current with very low noise. All these combined allow us to guarantee very narrow linewidths of less than 200 kHz measured over 50 milliseconds.
Computer Control and LabVIEW™ Support
The TLB-6800-LN controller comes with both USB and RS-232 interfaces for optional remote control through a computer. We include a Windows application for plug-and-play control as well as Windows DLL and LabVIEW™ VI samples for greater programming flexibility. The TLB-6800-LN low noise controller allows you to easily fine tune and adjust the output power or bias current with 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 function generator to drive the piezo of your tunable laser with the built in function generator. The TLB-6800-LN controller has easy to access front panel controls with an included output to synchronize with other devices.
Star-Flex Actuation
The Vortex Plus is New Focus' most stable laser and uses the same Star-Flex actuation that was introduced in the popular Vortex II laser. Star-Flex is a motion actuation design like no other. 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 the patent-pending technique of magnetic damping providing minimal frequency jitter and drift.
