Abstract:Nanosecond lasers have recently been widely involved in human activity. However, high-intensity laser radiation can cause severe damage to organs of vision and expensive photonic devices. Radiation in the near UV range is especially dangerous for human eyes, since it is strongly absorbed by biological media and is also invisible, i.e., the reaction time of the eye to such radiation is much lower than that of visible light. Passive limiters have high transmission (>70%) at a low light intensity and begin to … Show more
“…During measurements of optical limitation, the cuvette with the substance was fixed at the focus of the lens. A more detailed description is presented in works 6,7 . The measurements were performed using a Nd:YAG laser Lotis TII LS-2147N at the second radiation harmonic λ = 532 nm with a single pulse duration τ = 20 ns.…”

“…The light intensity depends on the pulse duration, which can increase with time after a non-linear interaction with the material 7 . The intensity is proportional to the square of the amplitude of the electric field strength of the light wave:…”
