High power optically pumped vertical-exteal-cavity surface-emitting lasers with front and end pump are re-ported. The gain chip consists of 15 repeats of In0.26GaAs/GaAsP0.02 multiple quantum wells and 30 pairs of Al0.2GaAs/Al0.98GaAs distributed Bragg reflectors. The maximum output power of 3 W, optical-to-optical conversion efficiency of 22.4％, and slope efficiency of 29.8％ are obtained with 5-?C heatsink temperature under the front pump, while the maximum output power of 1.1 W, optical-to-optical conversion efficiency of 23.2％, and slope efficiency of 30.8％are reached with 5-?C heatsink temperature under the end pump. Influences of thermal effects on the output power of the laser with front and end pump are discussed.
