Quickly Formed Continuously Tuneable Laser in the Full Visible Spectrum Using Cholesteric Liquid Crystal Cells Based on the Electrothermal Effect (Laser Photonics Rev. 18(7)/2024)

Abstract

Cholesteric Liquid Crystal Laser Array

Wavelength-tunable lasers have a significant impact on various fields, and their applications are continuously expanding with advancements. A continuous wavelength tunable laser array can be formed in only 10 minutes by applying a voltage once to the cholesteric liquid crystal wedge cell. This laser device can generate continuous laser lines in the full visible spectrum. This strategy is expected to bring innovation to the development of future tunable laser devices.
