Abstract
A neodymium laser was constructed with a locally designed
circular cylindrical pumping cavity. Laser action was
achieved under conditions predicted.
A Nd:YAG crystal was selected for use in the laser, and
the physical and chemical properties of Nd:YAG as compiled
from the literature are presented. The theoretical and
experimental approach for designing the Nd:YAG laser system,
and a detailed description of the laser system are given,
with the expected operational characteristics extrapolated
from measurements on a commercial laser.
After a series of the tests, lasing action was observed
at the input power of 3.6 KW. The efficiency of the output
power to input was found to be 0.04% (slope) or 0.008% overall
approximately 20% of the values for a comparable commercial
laser. The low laser efficiency is ascribed to low cavity
pumping efficiency and inadequate cooling. Recommendations
are made for improvement of system performance.
