Researchers created a two-dimensional liquid crystal (LC) laser array by photopumping a single LC sample. This array offers a significant increase in energy density and potential for combined, high-quality output.

Area of Science:

  • Optics and Photonics
  • Materials Science

Background:

  • Liquid crystals (LCs) are versatile materials with tunable optical properties.
  • Developing compact and efficient laser sources is a key area in photonics.

Purpose of the Study:

  • To demonstrate a two-dimensional (2D) laser array using a single liquid crystal sample.
  • To investigate the coherence and output characteristics of the LC laser array.
  • To explore the generation of multiwavelength emission from LC lasers.

Main Methods:

  • Photopumping a single liquid crystal sample using a lenslet array of plano-convex microlenses.
  • Generating a 5x5 array of mutually coherent LC lasers.
  • Analyzing emission spectra with varying sample topologies.
