Evolution of the Tunable Laser

Tunable Lasers

In 1989, Santec became the world’s first manufacturer of single mode external cavity tunable lasers. Developing the technology over the years, we have optimized the lasers to have a high sweep speed, wide tuning range, narrow linewidth and low noise.

Ultimate Performance Tunable Laser

TSL-770

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)
TSL-770

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

Premium Performance Tunable Laser

TSL-710

Narrow linewidth, low noise and premium performance.

  • Excellent Accuracy (± 2 pm) & Resolution (0.1 pm)
  • Narrow Linewidth < 100 kHz
  • Wide Tuning Range from 1480 to 1640 nm
TSL-710

Combining high output power with high signal-to-noise ratio makes the TSL-710 an invaluable tool for optical testing. An innovative external cavity design has been implemented to lower the optical ASE noise, leading to a signal-to-noise ratio of over 90 dB/0.1 nm, while still maintaining a high output power of over +10 dBm. The TSL-710 is available for WDL and PDL measurement with our multi-port power meters (MPM series), a polarization control unit (PCU-100) and dedicated software. (Swept Test System)
