Tunable laser diode module Vortex™ Plus

continuoushigh-performanceautomatic

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. •Magnetic damping and Star-Flex™ actuation for highest stability •Fiber-coupled option •True mode-hop-free tuning •Narrow linewidth Wide Mode-Hop-Free Piezo Tuning The TLB-6800 Vortex Plus lasers feature very wide and guaranteed mode-hop-free piezoelectric transducer tuning ranges from 25-120 GHz with sub-picometer resolution. 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.
