For irradiation of a graphite limiter tile from the TEXTOR tokamak Nd:YAG 3.5-ns pulse laser with a repetition rate of 10 Hz and single pulse energy of up to 0,8 J at 1,06 µm has been used. The spectroscopy system allowed recording of spectra in the visible wavelength range including CII and Dα spectral lines. The evolution of CII and Dα spectral lines was observed pulse–by–pulse during the co–deposit removal. The efficient ablation of the 45 µm thick co–deposit occured after approximately 50 laser pulses.
