Abstract
The paper presents an optical device that permits dynamic limiting of the power of nanosecond pulsed laser radiation. Different possibilities to control the characteristics of optical limiters based on reverse saturable polymethine dyes with the use of schemes including lenses and diaphragms have been analyzed. It is proposed to change the geometric position of a dye cell relative to the focal region to control an operation threshold of the limiter. It is established that the efficiency of optical limiting may be improved using additionally the effect of thermal defocusing.
