ABSTRACT
Strontium carbonate deposition on copper substrate was carried out by the sedimentation method in order to produce yttrium-86. Natural strontium carbonate thick layer was prepared with 480 mg SrCO(3), 220 mg ethyl cellulose, and 7.5 mL acetone. This optimum condition is a result of several repeated experiments with different amount of ethyl cellulose and acetone. Target quality control was done by SEM photomicrograph and thermal shock test. The deposited target was irradiated at 30 microA current and 15 MeV proton beam for 12 min.

We report the operation of a laser diode pumped La(1-x)Nd(x)MgAl(11)O(19) laser mode locked by an electro-optic phase modulator. The repetition rate of the laser was 230 MHz, and the average output power was 50 mW, when pumped by a 500-mW broad-stripe laser diode. Transform-limited pulses of 14 ps duration were obtained. We have also demonstrated the FM operation of this laser, with bandwidths of up to 440 GHz being obtained.
