Flagship model high performance tunable laser
Santec has brought all its experience and knowledge gained over the past 30 years to its all-new 7th generation tunable laser. The TSL-770 is a very high specification tunable laser with flexibility in operation to ensure suitability for a wide range of applications. A ground up redesign of the laser cavity together with ultra-low noise electronics combine to provide market leading scan speed, high optical power, wide tuning range, low noise and narrow linewidth in the same laser. The new proprietary cavity design enhances Q-factor and wavelength stability enabling accurate measurements in even the most cutting-edge research applications.

v> Typical swept test system configuration
The TSL-770 has an internal power monitor that can be used to compensate output power fluctuation in real time. This eliminates the need to take an optical power reference and reduces the number of power meters required in a measurement system. The laser integrates with Santec’s power meter, MPM-210, and polarization controller unit, PCU-100, to create a turn-key WDL or PDL measurement solution. Santec provides software to control the system, as well as dynamic link libraries (DLLs) to enable system integration and control with a variety of programming languages.
