Intense Excitation Source for High Power Laser.
Abstract
A high power blue-green dye laser has been pumped with an array of multiple-stage hypocycloidal-pinch (HCP) plasmas. The maximum untuned laser power obtained with LD490 dye exceeded 230kW with a pulse width of 1.0 microseconds (FWHM). The HCP pump source was energized by up to 4.2 kJ energy which was stored in the capacitor bank. The plasms temperature 7,250 K was obtained when the HCP was operated for the optimum laser output, The spectral efficiency of the absorbed radiation was 22% or 83% of the maximum efficiency of the optimum blackbody source. Finally the enhancement of LD490 dye laser output energy has been attemped with the spectrum conversion of HCP pumping light, The result indicates that the secondary dye BBQ enhanced laser output of LD490 dye by a factor of two. Keywordws include: Hypocycloid-pinch plasma, Blue-green Laser, LD490 dye, Iodine laser, Spectrum conversion of HCP pumping light.
