研制了一种新型端面泵浦之字形板条结构的Yb：YAG激光器。该架构提供了均匀的横向泵浦轮廓、激光晶体的传导冷却、机械坚固性以及可随时扩展到更高功率。在室温下，激光器连续输出功率为415W，光转换效率为30%。反像稳定腔可获得252W的高亮度输出，线偏振，平均M(2)光束质量为1.45。获得了高达20mJ的调Q脉冲能量和高达150W的平均调Q功率，同时M(2)保持在<；1.5。
A diode-pumped Yb:YAG laser with a novel end-pumped zigzag slab architecture has been developed. This architecture provides uniform transverse pump profiles, conduction cooling of the laser crystal, mechanical robustness, and ready scalability to higher powers. At room temperature the laser emits 415 W of cw power with 30% optical conversion efficiency. An image-inverting stable resonator permits a high-brightness output of 252 W with linear polarization and an average M(2) beam quality of 1.45. Q-switched pulse energies of as much as 20 mJ and average Q-switched powers of as much as 150 W were obtained while M(2) was maintained at <1.5.
