Abstract
With pumping by a Ti:sapphire laser, the cw laser characteristic of a , cleavage microchip in an end-pumped plano–plano resonator is researched. A slope efficiency of up to 49% and a maximum output power of are obtained at an absorbed pump power of and an optimal output coupler transmission of 3.2%. Choppers with different duty cycles are used to change the thermal effects in the microchip, and the influences of thermal effects on the laser characteristics of the cleavage microchip are investigated.
