Leonid M. Goldenberg, Victor Lisinetskii and Sigurd Schrader Stable Lasing in Azobenzene Polyelectrolyte with Polarization Gratings as Distributed Feedback Advanced Optical Materials 1
Thin film distributed feedback lasers based on azobenzene polyelectrolyte and polarization gratings emit from 640 to 870 nm. Some of the lasers exhibit remarkable half lives of a few tens of thousands of pulses without encapsulation. The lasers emitting in the 1st diffraction order show a higher efficiency and a lower lasing threshold.
