Interaction of 0.53 μm laser pulse with millimeter-scale plasmas generated with gas-bag target

Reported are the interactions of 0.53 mu m laser pulse with millimeter-scale plasmas that are produced with gas-bag target irradiated with 0.35 mu m laser pulses. The generated plasmas are characterized with collective Thomson scattering and space- and time-resolved X-ray images. The density of the...

Description
Summary:Reported are the interactions of 0.53 mu m laser pulse with millimeter-scale plasmas that are produced with gas-bag target irradiated with 0.35 mu m laser pulses. The generated plasmas are characterized with collective Thomson scattering and space- and time-resolved X-ray images. The density of the plasmas is about 0.1 n sub(c)orresponding to the 0.53 mu m laser beam, and the temperature is about 0.64 keV with a filling gas of C sub(5)H sub(12). The interaction laser beam can output 1.0 kJ energy within the duration of 1 ns at the wavelength of 0.53 mu m, leading to a nominal intensity less than 1.5 x 10 super(15) W/cm super(2). The reflectivity of stimulated Brillouin scattering (SBS) and stimulated Raman scattering (SRS) is measured with a full aperture backscatter system. The experimental results show than the reflectivity of SBS is less than 5% and that of SRS is less than 1%. It is a positive result with respect to using 0.53 mu m lasers as drivers for laser fusion.
