Manufacturer: Spectra-Physics — USA
Overview
The New Focus Venturi TLB-8800 swept-wavelength lasers combine the best in tunability, offering ultrafast, ultrawide, and mode-hop-free wavelength sweeping with low noise, high accuracy, and repeatability. Built on Spectra-Physics' award-winning laser design, Venturi lasers deliver OEM-proven 24/7 reliability with wavelength tuning speeds up to 20,000 nm/s, programmable high frequency repetition rates, and programmable coherence control. Venturi lasers are ideal for fiber sensing, fiber-optic and silicon photonics testing, spectroscopy, laser seeding, and metrology.
High-Speed Wavelength Sweeping
The Venturi TLB-8800 is the only swept-wavelength laser offering tuning speeds up to 20,000 nm/second along with high frequency repetition rates, enabling true real-time measurements.
Flexible Tuning Modes
In addition to wavelength sweeping, the Venturi is capable of step tuning in 0.01 nm increments, with adjustable tuning speeds, repetition rates, dwell times, and wavelength ranges to suit unique measurement needs.
