Velocity™ TLB-6700 Wide and Fine Tunable External Cavity Diode Laser 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, thermally insulated with active temperature control, and incorporates our unique magnetic damping technology to provide 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 fiber coupling are integrated within the laser housing to ensure the highest power stability. The Velocity is operated using the TLB-6700-LN controller designed with low-noise analog circuits. The laser head is recognized upon startup, and optimum temperature, maximum current limit, and tuning range are automatically set. Current limits and safety shutoff features ensure maximum diode lifetime. Integrated wavelength monitoring allows adjustment to within 0.01 nm, and piezo fine tuning provides even finer sub-picometer precision. External control and frequency locking are possible via analog input ports, and operation in both manual and remotely programmed modes is accessed via a USB interface. The Velocity TLB-6700 Advantage • True mode-hop-free wide tuning • Exceptional stability with shock-proof and thermally insulated housing and magnetic damping technology • Fiber coupled option with robust, permanent fiber coupling • Easy-to-use wavelength control Applications • Spectroscopy • Micro-cavity resonators

1. Due to our continuous product improvement program, specifications are subject to change without notice. 2. Motorized wide tuning and PZT fine tuning. Contact us for other available wavelengths and typical tuning curves. Wide tuning is mode-hope-free in constant current mode only. 3. Resolution is 10 mV in PZT (0.01% of full PZT tuning range) through controller front panel or command interface. When tuning PZT using an external voltage source through External Frequency Modulation input, resolution is dependent on voltage source. 4. Current modulation directly to diode through laser head SMA...
