Abstract
Laser ablation of solid targets by Ti:sapphire laser radiation is stud ied. The targets are irradiated by 150 fs-5 ns laser pulses with a flu ence in the range of several J/cm(2). Measurements on the ablation dep th yield an effective penetration depth higher than the optical penetr ation depth. Advantages and potentials of sub-picosecond laser radiati on for the ablation and for the microstructuring of metals are demonst rated.
