| Abstract: | We demonstrate a simple method that can be used to detect minor isotope lines in a saturated absorption spectrum by the absorption
filtering of major isotope lines. We investigate this method for use in the spectroscopy of the 1S0-1P1 transition in Yb at 399 nm by controlling the density of Yb atoms by varying the discharge current of a hollow cathode lamp.
The performance of an extended-cavity laser diode using a high-power ultraviolet diode chip is also analyzed. |
