Tropospheric temperature profiles have been measured at daytime with a rotational Raman lidar. The lidar operates in the solar-blind spectral region with KrF laser radiation that is Raman shifted in hydrogen to 276.787 nm. This wavelength corresponds to the resonance absorption of a thallium atomic-vapor f ilter that is used to suppress the large(More)
Various configurations of a tunable two-stage KrF laser have been investigated for providing powerful laser pulses with very low amplified spontaneous emission (ASE). The lowest fraction (0.00017%) of ASE was attained with a single-pass amplifier and a phase-conjugate Brillouin mirror. The most suitable application envisaged for the laser source, i.e.,(More)
