Abstract

A random laser system includes critical Solution Temperature (CST) material, either a Lower CST (LCST) or an Upper CST (UCST) material, in combination with an optical gain medium (20), such as a laser dye. A laser-like emission is observed in response to optical pumping (12) only when the CST material is in a scattering state. The random laser is suitable for being microencapsulated (10), and can be used for, as examples, remote temperature (14) sending applications as well as for visual display applications.
