We have applied a combination of laser excitation and electric-field detachment to negative atomic ions for the first time, resulting in an enhancement of the excited-state detection efficiency for spectroscopy by at least 2 orders of magnitude. Applying the new method, a measurement of the bound-bound electric-dipole transition frequency in (192)Os- was performed using collinear spectroscopy with a narrow-bandwidth cw laser. The transition frequency was found to be 257.831 190(35) THz wavelength 1162.747 06(16) nm, wave number 8600.3227(12) cm(-1), in agreement with the only prior measurement, but with more than 100-fold higher precision.
