Diffraction-limited broadband optical meta-power-limiter

Optics Letters, 2021
In recent years, the need for a high-power laser has been of great interest for different applications, including direct-laser processing, light detection, medicine, and lighting. However, high-power lasers with high intensities give rise to fundamental problems for optical detectors and imaging systems with low threshold damage, which still need ...

MEMS-based optical limiter

Applied Optics, 2008
We propose the design of an optical limiter based on a microelectromechanical systems deformable mirror. The design is based on aperturing focused light reflected out of an optically driven deformable mirror, deformed in a parabolic form. We derive an expression for the reflected light intensity, and we show that the reflected light saturates as a ...

Nonlinear optical beam propagation for optical limiting

Applied Optics, 1999
We implement numerical modeling of high-energy laser-pulse propagation through bulk nonlinear optical materials using focused beams. An executable program with a graphical user interface is made available to researchers for modeling the propagation of beams through materials much thicker than the diffraction length (up to 10(3) times longer).

Optical Limiting Applications

2002
Most promising applications of C60 fullerene are in the field of optoelectronics and nonlinear optics (NLO). Photovoltaic cells and infrared detectors are among actively pursued optoelectronic applications while, in the field of NLO, after some initial emphasis on third-order responses, such as intensity dependent refractive index, the focus is now ...

Photorefractive Optical Limiters

MRS Proceedings, 1994
AbstractWe consider the application of photorefractive beam fanning as an optical limiter. Results indicate that by focusing the incident laser light into the photorefractive crystal and by applying electric fields that limiting is possible at the 10μJ range with an optical density or O. D. of 3.
