FIG. 1.

Schematic illustration of the experimental setup. Energy resolved electrons were detected using an imaging plate. A forward scattered light spectrum and a side scattered light image were also measured simultaneously. A shadowgraph of the plasma using a probe pulse was observed to determine the focal position of the laser pulse.

FIG. 2.

The electron energy spectrum in both cases A and B. In case A, monoenergetic electrons were observed at a plasma density of . The energy of the monoenergetic electrons increased to in case B for a plasma density of .

Image of FIG. 3.
FIG. 3.

The plasma density dependence of the electron energy spectrum in case A. The monoenergetic electrons were generated at specific plasma densities. The laser power was fixed at . Other conditions are listed in Table I. The monoenergetic peak at for a plasma density of was observed.

Image of FIG. 4.
FIG. 4.

The plasma density dependence of the electron energy spectrum in case B. The laser power was fixed at . Other conditions are listed in Table I. The monoenergetic peak at for a plasma density of was observed.

FIG. 5.

The energy of the monoenergetic peak as a function of the plasma density. Results of case A (squares), case B with the laser power at (circles) and case B with (crosses). The solid lines are maximum electron energies given by Eq. (1) for and .

FIG. 6.

The number of electrons of the monoenergetic electron beam as a function of the laser power in case B. The open circles are the number of electrons from the average of an accumulation of laser shots. The closed circles are the number of electrons obtained from single shot measurements.

Image of FIG. 7.
FIG. 7.

The plasma density dependence of the spectrum of the transmitted laser light in case A. Transmitted laser light spectra around were blocked using a high reflection mirror, except for the spectrum at a plasma density of . The first Stokes satellite induced from the modulation of laser light by the plasma wave was observed. The experimental conditions are the same as that in Fig. 3.

Image of FIG. 8.
FIG. 8.

The spectra of the transmitted laser light for several plasma densities in case B. Transmitted laser light spectra around were blocked using a high reflection mirror. The experimental conditions are the same as that in Fig. 4.

Image of FIG. 9.
FIG. 9.

(a) The plasma density dependence of the shot-by-shot intensity ratio of the first Stokes satellite to the transmitted laser light. (b) The shot-by-shot spectral width of the first Stokes satellite in full width including substantial structure as a function of the plasma density. The experimental conditions are the same as that in Fig. 8.

Image of FIG. 10.
FIG. 10.

(a) A typical side scattered light image at a plasma density of with OAP (case B). The laser pulse was injected from the left-hand side of the image. The nozzle diameter indicated by a white dashed circle is . (b) The length of the side scattered light image as a function of the plasma density in case A (squares) and case B (circles). Experimental conditions for both cases are the same as that in Figs. 3 and 4. The arrows indicate the image length when the monoenergetic electron beams were observed.
