[摘要]：A system of three external cavity diode lasers is used to excite Rydberg states in rubidium. The 5S -> 5P -> 5D transitions are driven using lasers with lambda = 780 and 776 nm respectively. From the 5D state, atoms fluoresce down to the 6P state. The final transition to Rydberg levels is from the 6P state with laser light near lambda = 1016 nm. The nS and nD Rydberg states are accessible directly and with the application of a modest electric field nP states can also be excited. As a test of this system, Stark spectra are collected for nD and nP states. (C) 2011 Optical Society of America |
