A Cs vapour laser that utilises four laser diode arrays for longitudinal pumping of the gain medium is demonstrated. A maximum output power of 48 W was achieved with a total optical to optical efficiency of 49% and a slope efficiency of 52%. This work shows that the diode pumped alkali lasers can be scaled to higher powers.
