Abstract
A recent Letter by Sparks and Sen challenges the viability of a recently proposed design for a commercial laser-fusion power plant. The basis for this challenge is the controversial theory of enhanced stimulated Raman scattering put forward by Sparks. This theory has been examined carefully. It is found to be in direct contradiction to both the classical and quantum theories of stimulated Raman scattering, and it is also in serious conflict with many experimental results.
