Direct diode pumped Ho:YAG generated laser pulses at 2.12 μm with an optical to optical slope efficiency of 0.24. Ho:YAG and Ho:LuAG laser rods were evaluated with both wide and narrow bandwidth pump diodes. The laser wavelength varies with the leve

The drive-laser system of the photoelectric injector for the Los Alamos free-electron laser (FEL) is described. The bright electron beams required for high-performance FELs demand stringent specifications on the drive-laser output levels, beam qualit

In this paper the results of a simple experiment designed to study refraction‐induced distortion of images of narrow‐band‐light‐emitting regions in a laser‐produced plasma are described. Source regions were formed by relaying the image of a

The authors discuss the application of self-phase modulation and grating pulse compression to the generation of optical pulses suitable for controlling the electron beam emittance and energy spread in a FEL (free-electron laser) photoelectron injecto

A kinetic model which simulates ultrafast processes by numerical integration of rate equations based upon a homogeneously broadened two level system is compared with experimental results obtained by picosecond spectroscopy experiments. Application of

An optically generated transient absorbing state in the polymethine pyrylium dyes EK 9860 and 9740 is described. The broadband absorption is produced when solutions of the dyes are irradiated by a 1060 nm picosecond duration pulse. The absorbing stat

The ultrafast modification of molecular electronic state populations by picosecond duration laser pulses is discussed. The photodynamic interactions operative during the dual pulse irradiation of a saturable absorbing dye are treated by a rate equati

We have studied the energy‐resolved decay of benzophenone in the gas phase at various pressures. In the ``isolated‐molecule'' case benzophenone is shown to exhibit the characteristics of strong coupling between the S1 and T1 vibronic levels. A sm

This paper describes the generation of a continuum which has a time duration equal to or less than the picosecond pulse which generates it. The spectrum of the continuum is several thousand wavenumbers in width. Experimental methods are presented whi
