Picosecond CO 2 laser pulses and their applications
Abstract
The mechanisms for the generation of variable picosecond duration CO 2 laser pulses using the optical free induction decay method are reviewed. A few recent applications of the variable duration feature are described. They include the measurement of the T2 relaxation time in a CO 2 laser medium, the measurement of multiphoton absorption in sf 6 and the determination of the electron-phonon interaction time in a semiconductor.
