Abstract

Backscattered 2 ω and 3 ω/2 harmonics were investigated during the interaction of femtosecond radiation ( λ=795 nm, t=150 fs, 10-Hz pulse repetition rate) with various targets. The harmonics were generated inside the drilled hole without changing the position of target from shot to shot. No 3 ω/2 harmonic was generated in the case of single shots irradiated the fresh surface of the target. Various characteristics of harmonic radiation were analyzed and their dependences on pump radiation parameters were discussed.
