    It has been shown experimentally that xenon filled flashtubes are more efficient for pumping Nd3+doped YAG lasers than krypton flashtubes in spite of the higher output of the krypton flashtube at 0.810 microns. View full abstract»

    Anti-Stokes emission in sharply defined cones has been observed from fine filaments in a mixture of acetone with 5 to 10 percent CS2. The cone angle is in agreement with the momentum-matching condition that the longitudinal but not the transverse components sum to zero. View full abstract»

    The exact solution describing steady-state resonant pulse propagation in a two-level inverted medium is given. This steady-state pulse is often referred to as a 180° or π-pulse. No approximation of a slowly varying envelope is made, and hence the solution satisfies the second-order wave equation as well as the equations of motion of the density matrix of the system. As a result the theor... View full abstract»

    The possibility of phase locking the transverse modes of a laser is considered. It is shown that if a transverse mode set having a Poisson intensity distribution can be phase locked, a scanning laser beam can be produced. View full abstract»

    This paper describes a family of sealed-off, single-frequency, TEM00q-mode CO2lasers with output powers up to 15 watts. Short-term frequency stability[1],[2] measurements of the beat note of two free-running lasers in typical laboratory setups are discussed thereafter. The preliminary measurements indicate a short-term stability of about 5 parts in 1012for an obser... View full abstract»

    Irradiating a GaAs0.60P0.40laser with radiation from a GaAs laser demonstrates conclusively that the delay-inducing traps are deep centers which act as saturable absorbers. These centers can be filled optically and then remain in the nonabsorbing state for milliseconds. Their concentration is greater than 1 \times 10^{17} cm-3... View full abstract»

    Stimulated Raman scattering (SRS) from high-pressure H2gas was observed when giant-pulse ruby-laser radiation of frequency \tilde{\nu}_{0} = 14 398 cm-1, and its second harmonic of frequency 2\tilde{\nu}_{0} , were simultaneously focussed on the sample. The well-known SRS from H2was obser... View full abstract»

    Laser action during the active discharge at λ's 5454 and 5641, and during the late afterglow at λ's 5936, 6246, and 7039 in a high current pulsed discharge containing tellurium vapor and neon is reported. The afterglow transitions belong to the spectrum of TeII, but the assignment of the active discharge lines is uncertain. View full abstract»

    Results are reported on a passive Q -switched ruby laser utilizing a special rooftop prism cavity. With a 40 cm long resonator, a single transverse and longitudinal mode has been obtained. With a 3 meter long resonator, a single transverse mode self-locked beam has been obtained. View full abstract»

    The electron beam scanlaser (EBS) is a device in which a modified electrooptic light valve is used as a mode selector in the highly degenerate flat-field conjugate laser resonator to provide a scanning light spot. This paper describes improvements in the mode selection portion of the EBS which make the device far more promising. In particular, 1) the charge storage time is now under control, and c...
