ORGANIC THIN FILM LASER WITH TUNEABLE BRAGG REFLECTOR

摘要

A thin film laser is provided in which a peak wavelength of the thin film laser can be film laser dynamically tuned by applying a colloidal array reflector on a gain material, such as material doped with a laser dye. The dye-doped gain material is disposed on an optically reflective substrate to form the thin film laser. An excitation source optically pumps a laser light at the thin film laser, and the laser light is reflected by the optically reflective substrate. The laser light reverses direction and provides optical feedback to achieve lasing of the dye.
