摘要/Abstract

摘要： Two-photon dissociation of BeH$^{+}$ ions is studied by detecting the fluorescence changes of Be$^{+}$-BeH$^{+}$ bi-component Coulomb crystal in a linear Paul trap. BeH$^{+}$ ions generated by an exothermic reaction between electronically excited Be$^{+}$ ions and residual H$_{2}$ in the vacuum chamber are photon-dissociated with two photons scanning over the range of 201 nm to 208 nm. Our experiment provides a novel method to maintain the number of Be$^{+}$ ions stable in a Coulomb crystal with a middle ultraviolet band dissociation laser. This two-photon dissociation method extends the wavelength range of the dissociation laser for BeH$^{+}$ compared to the one-photon dissociation, and the method can be utilized to all alkaline earth atomic ions which require suppression of the reaction with residual H$_{2}$ gas in vacuum.
