Abstract
The LASL CO2 laser fusion systems present some unique problems preventing successful utilization of conventional techniques. A few of them are: 1) use of tight spatial filters renders techniques based on ray tracing ineffective; 2) the spatial filters remove only certain aberrations and the saturable gain and loss media alter intensity distributions in a nonlinear fashion; 3) high and low Fresnel numbers are encountered at different parts of the system; 4) the use of state-of-the-art novel components like dia-mond point turned optical elements and 16-inch NaCl windows which degrade the nominally diffraction-limited performance; 5) the pulse being nominally nanosecond does not help. Hence, a custom tailored combination of programs' and a different approach (utilizing detailed examination of the Zernike polynomial set by which each component is characterized) appears necessary. An example using the LASL Two Beam CO2 Laser Fusion System is presented.
