Evolution of the Tunable Laser

Ultimate Performance Tunable Laser


Our highest accuracy, fastest tuning, lowest noise and narrowest linewidth laser.

  • 200 nm/s Rapid Sweep
  • Linewidth < 60 kHz
  • < 1/10 Frequency Fluctuation (vs. conventional model)
  • Fine tuning scan range 10 GHz



Our TSL-770 is the ideal choice for a wide range of applications, from production to basic research, due to its high speed, narrow linewidth, wide 160 nm tuning range and market leading accuracy and precision. A proprietary resonator design enhances Q value and wavelength stability, opening doors for photonic investigations in the most cutting-edge research applications.



  • Wide tuning range from 1480 to 1640 nm
    If you require a different wavelength range, please refer to the TSL-550 which offers more wavelength ranges, with options from 1260 to 1680 nm.
  • Mode-hop-free with rapid sweeps up to 200 nm/s
  • High output power > + 13 dBm
  • High signal-to-noise ratio > 90 dB/0.1 nm
  • High wavelength accuracy 0.3 pm(typ.)
  • Narrow linewidth < 60 kHz
