Abstract
We present what is, to the best of our knowledge, the first diode-pumped laser emitting at and below, based on the transition, generally used for a emission. A power of at has been achieved in cw operation and at with a fiber-coupled laser diode emitting at . Intracavity second-harmonic generation in cw mode has also been demonstrated with a power of at by using a nonlinear crystal.
