Figure 1.3 Fluorescence and laser spectra of nematic liquid crystal samples doped with 0.3wt% PM597. The emission peak spectrum is a random laser with a pump energy of about 1.2μJ. The embedded image is the relationship between the laser intensity and the angle θ between the linearly polarized light and the local nematic phase vector

Figure 1.3 Fluorescence and laser spectra doped with 0.3wt%PM597 phased liquid crystal samples. The spectra of the emission spikes are random lasers with pumped energy of approximately 1.2μJ. The inline diagram shows the relationship between laser intensity and linear polarized light and the angled crucity of the local column phase vector
