Fast Burning of Persistent Spectral Holes in Small Laser Spots Using Photon-Gated Materials.
Abstract
Extremely fast (30 ns) burning of detectable persistent spectral holes in 200 micron diameter laser spots is reported using a new photon gated donor acceptor material: a derivative of zinc tetrabenzoporphyrin as a donor with chloroform acceptors in a poly (methyl methacrylate) thin film. The fast burning pulse near 630 nm was accompanied by a 200 ms gating pulse at 488 nm to produce the 1% deep spectral holes in transmission. This result illustrates one crucial advantage of photon-gated materials over single-photon materials: greatly increased reading fluences can be tolerated, allowing fast burning in small laser spots to be easily detected. Keywords: photon gating; frequency domain optical storage; Persistent spectral hole burning; electron transfer; fast burning.
