The Slim Liner is the single frequency laser that offers an intrinsic optical linewidth narrower than 1 Hz, ultra-low phase/frequency noise as well as shot noise limited relative intensity noise above a few hundred of kHz. It includes UTI grid single frequency lasers, optically referenced single frequency lasers, and tunable single frequency lasers. Other wavelengths are also possible on request.


  • Ultralow frequency noise
  • < 1Hz Lorentzian linewidth
