Optical power limiting for eye protection from tunable lasers

PDF Version Also Available for Download.

Description

Reversible saturable absorption of C{sub 60} and sacrificial mirrors with double path were examined for eye protection from laser beams of picosecond and nanosecond lasers. Both approaches can achieve significant attenuation to protect eyes from serious or permanent damage although the clamped energy is still higher than the permissible values of ANSI standards. The combination of these two approaches can eliminate the need to replace sacrificial mirrors. The phenomena of absorbing 100 photons in a single picosecond pulse definitely deserves further study for its mechanism.
