High Performance Tunable Laser
The TSL-550 is a high performance tunable laser with a wide tuning range and an output combining high power and high signal-to-noise ratio. The mod-hop-free tuning TSL-550 is equipped with features such as fine tuning and coherence control making it a must have tool for precision optical testing. Santec has used an innovative cavity design to lower the optical ASE noise, resulting in an extraordinarily high signal-to-noise ratio of over 90dB/0.1nm, while also maintaining a high output power of over +10dBm. GPIB and USB interfaces with the industry standard SCPI command set provide a convenient automated measurement solution.
The TSL-550 has two separate versions: Type A includes a wavelength meter with ±20pm wavelength accuracy and Type C, the high accuracy version, with an absolute wavelength accuracy of ±5pm.
The TSL-550 is ideal for next generation components testing driven by innovations in Dense Wavelength Division Multiplexing (DWDM), passives and Wavelength Selective Switches (WSS) that require characterization of multi-input, high extinction ratio devices. The TSL-550 is designed to improve production inspection throughput by doubling the scan repetition rate over conventional lasers. In addition, the TSL-550 is available for WDL and PDL measurement with the support of our power meter, MPM-200 and dedicated software.
