Analysis of the Sun Pumped Laser Cone Optics.
Abstract
A meridional ray analysis is accomplished on the solar energy collector part of a sun pumped laser. A Gaussian approximation is completed and shows a solar image 0.57 inches in diameter is located 3.81 cm from the end of the laser rod. The image is inside the laser cavity. For 200 watts available at the primary mirror of the Cassegrainian System, it is found that only about 150 watts is furnished to the cone lens for through put. Only about 66% of the available 150 watts is collected by the cone lens and channelled to the laser rod by the condensing cone. The last is found by a skew ray analysis of some rays coming from the outer radial part of the primary mirror. These rays are traversing the system all the way to the cone lens, but are diverging before entering the lens and therefore not being collected by the condenser cone. An analysis is made of the exit angle of the power traversing the condenser cone. The analysis was made so that an AR coating of the appropriate material and thickness could be put on the laser rod for maximum collection of the solar energy wavelengths used in pumping the Nd:YAG laser rod.
