| Popis: | Intra-cavity second harmonic generation in a ring dye laser using lithium formate monohydrate has been observed to produce tunable cw UV radiation around 243 nm with single frequency powers of up to 1.4 mW. This wavelength region is of particular interest in the context of Doppler-free spectroscopy of atomic hydrogen. The radiation was used to excite an atomic beam of strontium to study the transition 5s 2 1 S 0 -4d5p 1 P 1 of Sr I. The isotope shifts were determined as follows: 88 Sr- 87 Sr 123.7(8) MHz; 88 Sr 285.0(8) MHz; 88 Sr- 84 Sr 600.1(9) MHz. The values are compared with results for other lines and muonic isotope shifts to obtain the specific mass shift and field shift in this transition and to study the configuration mixing effects. The hyperfine structure of 87 Sr was not resolved, the intervals being very much less than the measured linewidth of 25 MHz. |
