Abstract
We describe the continuous-wave (cw) operation of a LiYF4 laser based on crystals doped with different concentrations of Tm3+. We observed t he fluorescence spectra from the upper laser level when the crystal is placed inside the laser resonator, in the same optical environment of the coherent emission. We measured the laser intensity as a function of pump power and obtained a 24% slope efficiency by selecting a suita ble orientation of the crystal. Using all this information, we were ab le to demonstrate laser tunability at 1.9 mu m in a 50 cm(-1) wide int erval.
