We demonstrate a passive Q-switched at 2 um region by integrating Bismuth (III) Telluride (Bi2/Te3) embedded in Polyvinyl Alcohol (PVA). Bi2Te3 was embedded in PVA by solution casting approach to develop a Bi2/Te3-PVA film and integrated in the laser cavity with ring configuration to generate pulse...
