【 摘 要 】

We discuss a new approach to the implementation of laser action in silicon and other indirect band gap semiconductors - two-quantum photon-phonon laser. Dynamics of the photon-phonon laser generation in indirect band gap semiconductors with electron population inversion is investigated in detail with aid of the rate equations. Numerical estimates are made for Si and Ge.
