PLASMA EXPANSION UNDER HEATING BY A CO2 LASER PULSE
This paper treats the expansion of a gas breakdown plasma produced in argon by the focused radiation from a high-voltage transient-pumped CO2 laser. With the long pulses attainable from such pulsed CO...

We have investigated laser oscillation in periodic structures in which feedback is provided by backward Bragg scattering. These new laser devices are very compact and stable as the feedback mechanism is distributed throughout and integrated with the gain medium. Intrinsic to these structures is also a gratinglike spectral filtering action. We discuss periodic variations of the refractive index and of the gain and give the expression for threshold and bandwidth. Experimentally we have induced index periodicities in gelatin films into which rhodamine 6G was dissolved. The observed characteristics of laser action in these devices near 0.63 µm are reported. ©1971 The American Institute of Physics
