The TLB-6728 external cavity tunable diode laser features a 1520-1570 nm tuning range, and 30 mW of output power at 1550 nm. 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 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.
