Abstract: (2288 Views)
In this investigation, the effect of Nodular defects in Laser Induced Damage Threshold of optical filters was discussed. For this work, BK7 substrates were used. After substrate cleaning, high reflection coating was performed on substrates in 1064 nm wavelength. Then, Nodular defects were researched by AFM, SEM and optical microscopes. Finally, The Laser Induced Damage Threshold (LIDT) test was performed by 16 mj Nd:YAG pulsed laser, by 160 µm diameter in beam waist, in 1064 nm, for all samples. Finally, Damaged places were investigated by optical microscopes(Zeiss).
