Interactions of Intense 2.7 μm Picosecond Laser Pulses with Germanium

Source

Computer simulations of the generation and temporal evolution of hot plasmas in germanium during the passage of intense picosecond laser pulses have been begun. At 2.7μ two-photon absorption is the generating mechanism for carriers. Carrier heating from free-carrier absorption and energy transfer to the lattice through phonon-carrier collisions are described with an electron-hole band model similar to one previously used to describe plasma dynamics in germanium driven by one-photon absorption. Details of this model will be presented and the results available to date will be discussed.
