Single‐, Dual‐, Triple, and Quadruple‐Wavelength Surface‐Emitting Lasing in Blue‐Phase Liquid Crystal (Adv. Mater. 9/2022)

Abstract

Organic Lasers Single-, dual-, triple- to quad-wavelength lasers can be flexibly manipulated based on polymer-stabilized blue-phase liquid-crystal film, by tuning the bandgap, resonance cavity, order parameter of the laser dye, and even the pump energy. The single-to-quad-wavelength surface-emitting lasers proposed by Feng Jin, Jingxia Wang, and co-workers in article number 2108330, can be employed as coherent light sources for next-generation optical devices.
