The new N7779C basic line tunable laser source, like the other new N777xC models, can step quickly to discrete wavelengths with a resolution of 0.1 pm and a typical wavelength repeatability of ±3 pm, making it ideal for cost-effective testing of broadband optical devices. With wavelength setting times like 300 ms, rapid stepped sweeps are possible. Like the other lasers in the N777xC family, it delivers more than +12 dBm peak output power with low spontaneous emission levels. At ±0.01 dB power stability over an hour, it can also serve as a static local oscillator with a wide tuning range for receiver testing or transmission experiments.

The wavelength tuning performance has been enhanced to provide default fine tuning without overshoot. No separate fine-tuning control is needed for smooth tuning with 0.1 pm resolution, due to automatic coordination of the motor and piezoelectric-actuator. This simplifies wavelength-optimization procedures.

All N777xC tunable lasers are based on a common cavity and laser module design and share a narrow linewidth, excellent long-term stability and low spontaneous emission level. They are software compatible with the 8160xA and 81600B lasers, the industry standards for more than a decade, but occupy 1 height unit less rack space. The remote user interface on the instrument is accessible with just a web browser, either via LAN or via USB connection. An optional touch-screen display provides local operator access and displays current operating parameters.
