SAFE Technology

Dealing simultaneously with several lasers can become a nightmare when mode-hops prevent you to make long-term measurements. That’s why offering stable lasers is now a MUST for all complex lasers systems used in Quantum Computing, Quantum Sensing or Quantum Simulation.

The SAFE technology was developed with this in mind. It allows the new variant DL pro SMC to run stable for a long period; the user can now focus on the next technical challenges he faces.

Using TOPTICA´s novel SAFE technology, the new variant DL pro SMC (Single Mode Control) can find the center of the closest single mode plateau at a desired operating point at the touch of a button. The laser can then remain on this single mode plateau (SMC Lock) through an active stabilization of the external modes of the cavity onto the internal modes even under changing environmental conditions. The SAFE technology is based on TOPTICA´s proven DL pro resonator, adding a SMC detection unit. The detected signal changes with e.g. varying temperature, humidity and air pressure, thus enabling to implement a control loop for stabilizing the laser modes and avoiding mode-hops.
