摘要

We report on a widely tunable,narrow linewidth operation ofa Tm:YAG ceramic laser.A volume Bragg grating is used in the cavity as a folding mirror for wavelength selection.The wavelength is tuned from 1956.2 to 1995 nm,leading to a total tuning range of 38.7 nm.The linewidth is around 0.1 nm over the whole tuning range.A maximum output power of 1.51 W at 1990.5 nm is achieved at 37.8 W absorbed pump power.Different saturation behaviors are observed in the laser performances at different wavelengths.
