Abstract:
It is established that the intensity of the Ha line in integral spectra of a specimen irradiated sequentially by 5–6 laser pulses with energy density ≤ 2–3 J/cm2 at ≤ 15–20 min intervals decreases, which is accompanied by the increase of the surface damage threshold and the decrease of the damage probability at pre-threshold intensity of the laser radiation. The effect retains 1–3 h after irradiation of alkyl halide crystal and the lifetime of optical elements fabricated from KCl is increased, on average, three times.
