US Patent No: 6795464

Temperature control of laser action in scattering media

---

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, such as a laser dye. A laser-like emission is observed in response to optical pumping only when the CST material is in a scattering state. The random laser is suitable for being microencapsulated, and can be used for, as examples, remote temperature sending applications as well as for visual display applications.
