Guaranteed Mode-Hop-Free Tuning Across Entire Tuning Range

The TLB-6700 Velocity guarantees single-mode, mode-hop-free tuning across the entire specified wavelength range. You can feel confident tuning the wavelength with absolutely no mode-hops. This is not the coarse tuning range. There is no coarse tuning, just smooth mode hope free tuning. Change the wavelength, and the laser will not mode hop.

Motorized and Piezo Control for Wide Scanning and Fine Tuning

A DC motor enables smooth motorized tuning across the laser's entire wavelength range for wide scanning. When you need to make very fine adjustments, the piezoelectric transducer allows for fine tuning over 20-100 GHz with sub-picometer resolution.

TLB-6728-P Fiber Coupled Tuning Range

Low Noise, Narrow Linewidth

The Velocity features powerful temperature control to reduce wavelength drift and power fluctuations. We have incorporated our unique magnetic dampening to stabilize the tuning arm and reduce vibrational noise. The accompanying TLB-6700-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.

Integrated Permanent Fiber-Coupling

The fiber-coupled versions feature an integrated optical isolator and a permanently fixed and aligned steel jacketed fiber, eliminating fiber misalignment to increase efficiency and maintain power stability. Additionally, the drop-tested and shock-proof housing ensures a robust system.
