Generation of 480nm cw light for Rydberg excitation of Rb
POSTER
Abstract
Our setup for generating tunable 480 nm light for Rydberg excitation is detailed. A laser diode is tuned to 960nm in an external cavity. The light from the diode laser is amplified through a tapered amplifier. It is then frequency doubled using a single pass PPLN crystal. We use a programmed FPGA to lock the diode to a Fabry-Perot cavity. The result is narrow linewidth cw light with sufficient intensity for Rb Rydberg atom excitation and Rydberg atom EIT experiments.
