 | Stable formation of multi-PW relativistic channels in underdense plasma, with the power exceeding 10,000 critical powers and the peak channel intensity in the 1O to the 23rd power W/cm2 range, can be established using an appropriate gradient of electron density at the first stage of the self- channeling, which initiates the process of stable multi-stage relativistic and ponderomotive self-channeling. |

| Ti:Al(2)O(3) represents an exciting new material with application to many areas including atmospheric research, laser radar, and spectroscopy. It is particulary suitable for short pulse generation, since it has a very large bandwidth. In the context of short wavelength high brightness sources, MCR technology Corporation has pursued the development of Ti:Al(2)O(3) as a system which can be frequency doubled or tripled to produce high energy picosecond and femtosecond duration pulses ... |

 | The availability of recently developed high brightness picosecond rare gas halogen sources permits the performance of a broad range of basic physical studies of high-lying electronic states of atomic and molecular materials. Moreover, the extension of the ultraviolet source technology to the femtosecond range will enable the generation of extreme physical environments, namely, coherent irradiation with an electric field amplitude, that are impossible to establish by any other known means. ... |

| Measurements related to important aspects of molecular energy transfer and vibrational relaxation in CO2 are continuing. Pressure dependence is determined in detail. Measurements of the motional narrowing of the line profile of the spontaneous vibrational Raman scattering in H2 are completed. Propagation of short pulses through a resonantly absorbing medium is studied both theoretical and experimentally. In this connection, transmission behavior of 10.6 micrometer CO2 laser radiation pulse is examined ... |
