The Study of the Interaction of Intense Picosecond Light Pulse with Materials. Investigation of Two-Photon Conductivity in Gallium Arsenide using a Nd: Glass Laser

reportActive / Technical Report | Accession Number: AD0727755 | Open PDF

Abstract:

The report describes studies of photoconductivity in single crystal GaAs via two-photon absorption of light quanta from either a Q-switched or mode- locked Nd glass laser. The results obtained with nanosecond light pulses are compared with those obtained with picosecond case. In the latter case, the transient response of the induced charge carrier accounts for the observed effects.
