Laser generation in the 2 μm spectral range is interesting for applications in mid-IR fingerprint applications, including remote sensing, gas detection, high resolution molecular spectroscopy, and medicine. Here, we review the different Tm3+-based waveguide lasers with emission at around 2 μm recently developed in monoclinic potassium double tungstates, including a CW mirrorless and the first Q-switched waveguide laser based on this ion. We also investigated the influence on the waveguide laser performance of the crystallographic plane on which the epitaxial active layer has been grown.
