Tunable Laser Sources

Alnair Labs offers narrow linewidth tunable laser (TLG-210) and polarization maintaining femtosecond mode-locked fiber laser(PFL-200). The TLG-series features <100kHz narrow linewidth C-Band or L-Band with wavelength tunability that is locked at ITU grid for applications such as coherent communication and long-range optical sensing. The PFL-series is a compact pulsed laser incorporating carbon nanotube mode-locker that produces transform-limited pulses with a typical pulse width of 450fs.   Alnair also offers a Broadband ASE Source for C-Band or L-Band with power outputs at >17dBm or >23dBm.
