An experimental investigation of a novel unstable laser resonator configuration is reported. The purpose of the novel configuration is to maximize the area that can be illuminated with uniform intense flux by a given laser device. This is accomplished by displacing the optical axis of the resonator to one edge of the optical cavity. The results indicate that the change causes no loss of device output power and has little effect on the beam quality. Additional experimental results are presented indicating the sensitivity of resonator performance to misalignment of the off-axis resonator.
报道了一种新型不稳定激光谐振腔结构的实验研究。这种新型结构的目的是使给定激光装置能够以均匀强光通量照射的面积最大化。这是通过将谐振腔的光轴移到光学腔的一个边缘来实现的。结果表明，这种改变不会导致器件输出功率的损失，并且对光束质量影响很小。还给出了其他实验结果，表明谐振器性能对离轴谐振器失准的敏感性。
