Description
The New Focus™ tunable external cavity diode lasers deliver true continuous mode-hop-free tuning. It 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. Thermal and finite element analyses led us to the Star-Flex design that provides stiff, reproducible rotational motion without any translation. The Vortex Plus includes an SMA port for direct to diode high speed current modulation. When ordering, please specify the exact center wavelength (to 10 pm) in vacuum. Part number includes complete laser system and the new TLB-6800-LN laser controller. Heads and controllers can also be sold separately.
