Hi Joe, the scale factor is used to multiply the imported optical generation of 1W into actual power, which is usually smaller due to small device. Power usually quantifies the enegy flow per second crossing a surface. Pulse, on the other hand, will depend on the time, which is energy concept. Usually the refractive index changes due to e-h carriers from optical absorption. Thus it might not be the energy quantity that matters. Please think over the physics and mechanism of such change.
