Simultaneous two-photon resonant optical laser locking (STROLLing) in the hyperfine Paschen--Back regime
Renju S. Mathew, Francisco Ponciano-Ojeda, James Keaveney +2
We demonstrate a technique to lock simultaneously two laser frequencies to each step of a two-photon transition in the presence of a magnetic field sufficiently large to gain acces…
