摘要 |
<p>A device for generating a high-energy particle pulse is provided which comprises a laser system producing laser pulses with pulse length shorter than 1 ps (picosecond), preferred shorter than 100 fs (femtoseconds), and capable to be focused to peak intensities greater than 10^18 W/cm^2, preferred greater than 10^20 W/cm^2 (watts per centimeter squared), a device for shaping the temporal intensity profile accompanying said at least one laser pulse for increasing the laser contrast above 10^5, preferably above 10^7, especially 10^10, and a target capable of releasing a high-energy particle pulse, particularly an electron or a proton pulse, upon irradiation with at least one of said laser pulses. A corresponding method using the device is also described.</p> |
