Abstract
The paper presents the results and the criteria followed in the design of a solid state laser operating in bust mode. Specifically addressed for a Thomson scattering diagnostic, the laser delivers at 1 urn a burst of 10 shots, each of 10 J, 15 nsec and pratically diffraction limited. Main problems are thermal effect which can cause un unaccettable change of divergence during the bust. It will be show that the simple scheme of nocooling turns out feasible. Effects of doping level, choise of Nd hosts together with choises of discharge electronic will be considered. An optimum choise proved to be the YLF oscillator and preamplifier, followed by a double pass zig-zag phosphate slab. Near field and far field pattern show a good point and divergence stability. Roughly speaking, we can say that an "overall induced thermal lens" longer than 40 m for the 2 cm output beam has been achieved.
