2 μm solid-state laser mode-locked by single-layer graphene

We report a 2 μm ultrafast solid-state Tm : Lu2O3 laser, mode-locked by single-layer graphene, generating transform-limited similar to 410 fs pulses, with a spectral width similar to 11.1 nm at 2067 nm. The maximum average output power is 270 mW, at a pulse repetition frequency of 110 MHz. This is a convenient high-power transform-limited ultrafast laser at 2 μm for various applications, such as laser surgery and material processing.
