Room‐temperature green laser emission of Er:LiYF4

We report the first demonstration of a green erbium‐doped crystal laser at room temperature. Excited with a pulsed dye laser, the erbium‐doped LiYF4 crystal emitted on the 4S3/2–4I15/2 ground state transition. As expected from fluorescence measurements, the emitted radiation was polarized parallel to the optical axis. Laser oscillation has also been observed in erbium‐doped Y3Al5O12 and Lu3Al5O12 crystals.
