Abstract

When a laser dye with high gain is dissolved into a system, which is comprised of hydroxypropyl cellulose (HPC), it makes a nice random laser system where scattering length and photon diffusivity can be temperature-controlled. Thus, the spectrum of the random laser output coming out of the front surface of the sample is observed with varying temperature. the results show linewidth narrowing from 30 nm to 5 nm and peak emission strength increasing by almost 10 times as temperature increases from room temperature to ∼48°C.
