Abstract
A Q-Switched Nd:YAG laser pulse of pulsed width of 9 similar to 14 ns, wavelength of 1064 rim, repetition rate of 0.5 Hz, power of 1.1 MW and energy of 10 mJ has been used to ablate the 4N pure graphite target through IR lens. Solid state nuclear track detector (SSNTD) CR-39 has been used to calculate the energy of carbon ions produced as a result of laser ablation and the whole experiment has been performed under pressure similar to 10(-3) Torr in stainless steel vacuum chamber. The minimum and maximum energy of carbon ions observed are 0.2KeV to 250KeV respectively.
