Frequency stabilization of 480 nm laser using two-photon DAVLL

Abstract

Abstract:

Frequency stabilization of a diode laser at 480nm is crucial for coherently exciting rubidium atoms to Rydberg states. Here reported is a laser laser frequency stabilization experimenttechnique techniques based on electromagnetically induced transparency in a ladder con?guration with a polarization spectroscopy stabilized 780nm diode laser as the probe laser and a 480nm laser as the coupling laser. With a uniform magnetic ?eld, a two-photon dichroic atomic vapor laser lock (DAVLL) spectroscopy iswas generated. Then this spectroscopy was and fed back through two proportion -integral -differential circuits to lock the 480nm diode laser. A combined linewidth of about 1MHz is achieved during the locking period.

Key words: laser techniques, laser frequency stabilization, two-photon dichroic atomic vapor laser lock, Rydberg transition
