Venturi TLB-8800

SWEPT AND STEP-WAVELENGTH TUNABLE LASER

Up to 20,000 nm/s wavelength tuning
Programmable high frequency repetition rates
Programmable coherence control
Continuous wave and single longitudinal mode

The New Focus™ Venturi TLB-8800 swept-wavelength lasers deliver it all. They combine the best in tunability – ultrafast, ultrawide, and mode-hop-free – with low noise, high accuracy and repeatability. Because Venturi lasers are based on our award winning design, they are extremely dependable with OEM proven 24/7 reliability. Venturi lasers are ideal for fiber sensing, fiber-optics and silicon photonics testing, spectroscopy, laser seeding, and metrology.

The Venturi TLB-8800 is the only swept wavelength laser with up 20,000 nm/second tuning speed and high frequency repetition rates enabling true real-time measurements. Tuning speeds, repetition rates, dwell times, and wavelength ranges are adjustable to accommodate your unique needs. In addition to wavelength sweeping, the Venturi is capable of step tuning in 0.01 nm increments. The front panel offers easy access to RS232 and USB interfacing with use of a user friendly GUI.
