Abstract [en]

We report record-high small-signal gain of 1050 dB/cm at 981 nm wavelength in a KGd<inf>0.425</inf>Yb<inf>0.575</inf>(WO<inf>4</inf>)<inf>2</inf> thin film. The sensitivity of gain to the shift of beam-focus position, which is critical under non-waveguiding conditions, is investigated.
