An Yb:YAG laser crystal containing 20% of Yb was pumped by a F{sub 2}{sup +}:LiF colour centre laser emitting in the spectral range from 0.89 to 0.95 {mu}m. We managed to pump 10% of a total amount of Yb ions to the {sup 2}F{sub 5/2} metastable level of ytterbium in small volumes of the optically dense Yb:YAG laser crystal, which corresponds to the energy density stored in the crystal equal to 30 J cm{sup -3}. Nanosecond pulses were generated at transitions between the Stark components of the {sup 2}F{sub 5/2} and {sup 2}F{sub 7/2} levels of Yb{sup 3+} ions at the wavelengths near 1.03 and 1.05 {mu}m. The possibility of using Yb:YAG crystals and ceramics in high-power laser drivers in laser fusion experiments is discussed. (lasers)
