Velocity™ TLB-6700 Widely Tunable Lasers
Velocity™ TLB-6700 Widely Tunable Lasers
The New Focus™ tunable external cavity diodes lasers lead the market with high performance, delivering true continuous mode-hop-free tuning over wide wavelength ranges. The Velocity TLB-6700 is our premier tunable diode laser system offering both wide and fine wavelength scanning. The laser cavity housing is shock proof and thermally insulated with active temperature control and incorporates our unique magnetic damping technology providing higher power, stability, and narrow linewidths.
The fiber coupled option includes a robust, permanently fixed fiber port for optimal coupling efficiency maintained across the wavelength tuning range. Both the isolator and coupling are within the laser housing to ensure the highest power stability.

Features
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
TLB-6728-P Fiber Coupled Tuning Range
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.
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.
