利用一个由两个腔内元件组成的腔体，一个布鲁斯特角切割Nd:YAG和一个KTP倍频晶体，证明了一种二极管泵浦的单轴模式内腔倍频激光器。在Nd:YAG上，260 mW的入射功率可获得高达4 mW的单端输出功率。阈值功率为入射到YAG上的31 mW二极管功率；因此，单模操作达到了大约8.5倍的阈值。在最高功率下，由于空间孔燃烧效应，激光容易受到多模操作的影响，但在大约5倍阈值以下，可以实现可靠的单模操作。>
A diode-pumped, single-axial mode, intracavity doubled laser has been demonstrated using a cavity consisting of only two intracavity components, a Brewster angle cut piece of Nd:YAG and a KTP doubling crystal. Up to 4 mW single-ended output power has been obtained for 260 mW incident power on the Nd:YAG. Threshold power was 31 mW of diode power incident on the YAG; thus, single-mode operation was attained at up to approximately 8.5 times threshold. At the highest power the laser was susceptible to multimode operation due to spatial hole burning effects but below approximately 5 times threshold reliable single mode operation was achievable. >
