Flagship model High performance Tunable Laser
Santec has brought all the experience and knowledge gained over the past 30 years, to the all-new 7th generation of their High Performance, High Speed TSL series tunable laser. A ground up redesign of the laser resonator and control electronics make the TSL-770 our fastest tuning, widest scanning, lowest noise and narrowest linewidth laser ever. With models available in the 1250-1650nm range, the flexible TSL-770 is ideal choice for a wide range of applications; improving throughput, accuracy and precision in production, R & D and basic research. A proprietary resonator design enhances Q value and wavelength stability, opening doors for photonic investigations in the most cutting-edge of research applications.

Typical Swept Test system configuration
IL / PDL measurement setup with the polarization controller PCU-100 and the power meter MPM-200
IL measurement setup with the power meter MPM-200
WDL/PDL measurements. The TSL-770 has a power monitor function that can be used to compensate output power fluctuation in real time. This feature is best recommended to be used with Santec's power meter MPM-200 and polarization controller unit PCU-100 as a turn-key WDL / PDL measurement solution. The software included in Santec's Swept Test System optimize measurements in order to achieve high power repeatability in WDL / PDL measurements.
