- Fluorescence studies of hematoporphyrin derivative (HPD) in normal and tumor tissue of rat were performed with nitrogen laser excitation and optical multi-channel detection. Fifteen types of tissue including inoculated tumor were investigated for rats at different delays after HPD injection. Optimum contrast functions and other criteria for discriminating tumor tissue from normal tissue are discussed. The results should have implications for practical human HPD endoscopy.

Gas-correlation lidar
- 1984
-
Ingår i: Optics Letters. - 0146-9592. ; 9:11, s. 493-495
-
Tidskriftsartikel (refereegranskat)abstract
- Basic principles for the extension of gas-correlation techniques to the lidar situation are discussed. Favorable signal-to-noise ratios and relaxed laser requirements characterize the technique. Preliminary experiments on atomic mercury are reported.

Tidskriftsartikel (refereegranskat)abstract
- Using time-resolved laser spectroscopy we have determined the hyperfine structure in the 3s2n p2P3/2 sequence of27Al (I=5/2). The magnetic-dipole interaction constants were found to scale withn*-2.85 (n* is the effective principal quantum number) in the investigated regionn=6–12. Significant quadrupole interaction constants were obtained forn=6–9. The measured radiative lifetimes forn=6–12 scale withn*2.

Natural radiative lifetimes in the 3 sns 1S0 and 3 snd 1D2 sequences of magnesium

Tidskriftsartikel (refereegranskat)abstract
- Natural radiative lifetimes have been determined in the determined in the 3 sns 1S0 (n=4-15) and the 3 snd 1D2 (n=3-15) sequences of Mg I employing a pulsed-laser system. The radiative lifetimes in the 1S0 sequence and of the higher members in the 1D2 sequence are unperturbed and scale as (n*)2.6 (where n* is the effective principal quantum number), while the lifetimes of the lower members in the 1D2 sequence are perturbed by the doubly excited 3p2 configuration. The measured lifetimes are compared with available theoretical calculations, and a very good agreement is obtained.
