Diode-end-pumped continuous-wave and acousto-optics Q-switched Tm:LiLuF(4) slab lasers were demonstrated. The a-cut Tm:LiLuF(4) slab with doping concentrations of 2 at.% was pumped by fast-axis collimated laser diodes at room temperature. The maximum continuous-wave output power of 10.4 W was obtained while the absorbed pump power was 31.6 W and the cavity length was 30 mm. For Q-switched operation, we got the maximum pulse energy of 8 mJ with pulse width of 315.2 ns at 1 KHz pulse repetition frequency.
