A system has been developed to deposit cells in indexed locations on a gelatin-coated film following flow cytometry, allowing the measurements made of individual cells to be correlated with observed morphology or with subsequent microspectrophotometr

The spectrum of resonantly scattered light at right angles to a sodium atomic beam is reported. The light source was a cw dye laser tuned to resonance with a hyperfine component of the Dz line, and incident at right angles to the atomic beam. The spe

The breakdown of gases under the influence of a laser beam is analyzed. Classical diffusion theory is taken as a model, with electrons accelerated by inverse bremsstrahlung until they have sufficient energy to ionize neutral gas atoms. Both diffusion

In careful experimental measurements of mode‐locked laser pulses, using nonlinear media, a number of workers have found evidence for what appear to be coexisting subpicosecond pulses, and pulses in the range of 10–40 psec. In this letter we descr

This paper presents the results of a study of the behavior of some saturable dye filters used with ruby lasers. We review some apparently contradictory results obtained earlier and present modified forms of energy level models, which are consistent w

We describe a tunable dye laser operating continuously in the range 570 nm to 620 nm. With a single prism and an intracavity etalon, single mode operation is obtained with a short-term bandwidth of less than 4 × 10-5nm (35 MHz) and a long-term stabi

The elastic properties of single‐crystal grains in polycrystalline material can be studied through Brillouin scattering using a laser probe beam. The Brillouin spectra of hot‐pressed CaF2 (Irtran‐3), having a typical grain size of 150 μm, is p

Various configurations for the successful operation of a continuous, tunable dye laser are described. Output powers as high as 100 milliwatts have been obtained using a 1.5 watt argon ion laser at 5145 A as the optical pump for the dye laser, with a
