Unformatted text preview: (bound electronhole pair). Use their definitions as given in Class Notes IV or Outline OII, where the inverse of this important product is given the name σ , and where it is noted that this product must be much less than 1 in order that the “FISH DIAGRAM” shown in OII be an accurate CW solution of the Model A equations. (2) the fraction f x of the entering electrons (and holes) that couple to form excitons inside the laser mode volume lwd . (3) the fraction F of the natural exciton decay events that result in the spontaneous emission of a photon. (4) The “Q” value of the laser mode....
