Laser induced moving dynamic grating in fluorescein doped boric acid glass thin films (10(-4) M).
Laser induced moving dynamics grating has been studied in fluorescein doped boric acid glass films in the limit of a weak probe and a relatively strong pump. The results have been interpreted in terms of the four-level description of a saturable absorber. Good agreement has been obtained in the experimental and the fitted results. Estimated values of the non-linear parameters such as the saturation intensity, refractive index, and also the response time of the optical non-linearity have been obtained at different strong pump beam intensity.
