Abstract

The hyperfine structure of the 4d2D3/2,5/2 levels of  69,71Ga is determined. The 4p2P3/24d2D3/2 (294.50-nm) and 4p2P3/24d2D5/2 (294.45-nm) transitions are studied by laser-induced fluorescence in an atomic Ga beam. The hyperfine A constant measured for the 4d2D5/2 level is 77.3±0.9 MHz for  69Ga and 97.9±0.7 MHz for  71Ga (3σ errors). The A constant measured for the 4d2D3/2 level is -36.3±2.2 MHz for  69Ga and -46.2±3.8 MHz for  71Ga. These measurements correct sign errors in the previous determination of these constants. For  69Ga the hyperfine B constants measured for the 4d2D5/2 and the 4d2D3/2 levels are 5.3±4.1 MHz and 4.6±4.2 MHz, respectively. The isotope shift is determined to be 114±8 MHz for the 4p2P3/24d2D3/2 transition and 115±7 MHz for the 4p2P3/24d2D5/2 transition. The lines of  71Ga are shifted to the blue. This is in agreement with previous measurement.

We have measured its second-harmonic-generation efficiency to be between 6×10−5 W/W2 and 2×10−4 W/W2. These numbers may not represent optimum second-harmonic-generation efficiency, as the focusing of the doubling cavity's waist was not optimized for this particular crystal.

The tunable UV laser was linearly polarized, and the saturation intensities calculated for the transitions between mF levels of the F=3→F=4 transition are 202 mW/cm2 for the mF=0→mF=0 transition, 215 mW/cm2 for the mF=1→mF=1 transition, 269 mW/cm2 for the mF=2→mF=2 transition, and 464 mW/cm2 for the mF=3→mF=3 transition. These values are typical of the other F→F transitions as well.
