• closedAccess   Lead-free FASnI3 laser amplifiers integrated in flexible waveguides 

      Suárez, Isaac; Chirvony, Vladimir; Sánchez-Díaz, Jesús; Sánchez, Rafael S.; Mora-Sero, Ivan; Martínez-Pastor, Juan P. Optica Publishing Group (2022)
      A FASnI3 lead-free perovskite is integrated in a flexible waveguide to demonstrate Amplified Spontaneous Emission. An extremely low threshold, 1 µJ/cm2, is observed together with the formation of narrow random lasing lines ...
