| Abstract | ||
| Optical coatings of dielectric materials of MgF2 and SiO2 have been used to reduce the effect electric field intensity of pulsed laser radiation and atmospheric conditions (oxidization) on metallic coatings (Ag and Au). The spectral characteristic of the reflectance curve for the preparation specimen in the visible and infrared regions in the range (400-1200)m were studied. The effect of incident radiation of Nd-YAG laser has been studied and the value of threshold was determined and equal (10-16J/cm2). The prepared reflectors and mirrors were used in construction of Q-switched Nd-YAG laser and to obtained the output pulses laser with energy(10-100mJ) and pulsed duration (30 ns). | ||
