Abstract

The investigation of dye-doped liquid crystal systems for lasing applications has become a burgeoning topic in recent years. To date, reports have been made of the tunability of cholesteric liquid crystal lasers by means of temperature, photochemical processes and mechanical forces. The application of an in-plane electric field on a cholesteric liquid crystal results in an unwinding and elongation of the cholesteric pitch. This change in pitch length shifts the reflection band of the cholesteric liquid crystal. We report on the tunability of a cholesteric liquid crystal laser in an in-plane switching mode cell. Tunabilities of up to 15 nm have been achieved in these cells. Electrical tuning methods have significant advantages over the other techniques by which cholesteric lasers can be tuned, especially with regards to the potential applications of liquid crystal lasers.
