Popis: The use of photoacoustic detection is discussed as a technique for monitoring laser heating and for characterizing implantation and recrystallization of semiconductors via optical absorption. Preliminary results are reported for laser heating of Ge. A method is proposed for signal processing to enable measurement of optical absorption coefficient changes due to implantation and recrystallization without a background signal from the unimplanted region of the semiconductor.
