  • Full-band TSL

Ultra-Wideband Tunable Laser

440 nm tuning, high performance tunable laser system.

  • Wide Wavelength Range 1240 to 1680 nm
  • Mode-hop-free wavelength sweeps
  • 200 nm/s sweep speed
Full band TSL


The system combines up to four of our tunable lasers (TSL-570) with an optical switch module (OSU-110) and control software. 

The complete Full-band TSL has excellent cost performance, high wavelength accuracy, and fast sweeping for use in both R&D and production environments.

Wide Wavelength Range

Ultra-wide tuning range from 1240 to 1680 nm (O-band to U-band)

Rapid Sweep Technology

Precise speed control up to 200 nm/s with high accuracy

Exclusive Software

Automated operation using Santec's exclusive software

Narrow Linewidth & Low Jitter

Isolated optical cavity results in linewidth < 60 kHz and high wavelength stability
