摘要: We demonstrate a three-step laser stabilization scheme for excitation to nP and nF Rydberg states in 85Rb, with all three lasers stabilized using active feedback independent Rb vapor cells. The setup allows the 36P3/2–70P3/2 33F7/2–90F7/2, only limiting factor being available third step power. study by monitoring frequencies simultaneously against self-referenced optical frequency comb. laser, locked transition, displays an Allan deviation of 30 kHz over 1 second <80 hour. is very robust affordable, it would be ideal carrying out range quantum information experiments.
