利用三束基频激光在汞蒸气中的和频，可以产生真空紫外122 nm（莱曼-α）连续相干辐射。其中一个基本光束的波长为254 nm，接近汞中的61 S 0 - 63 P1共振。实验研究了这种单光子共振对相位匹配、吸收和非线性产额的影响。连续产生莱曼-α的效率提高了4.5倍。
Continuous coherent radiation in the vacuum ultraviolet at 122 nm (Lyman-α) can be generated using sum-frequency mixing of three fundamental laser beams in mercury vapor. One of the fundamental beams is at 254 nm wavelength, which is close to the 61S0–63P1 resonance in mercury. Experiments have been performed to investigate the effect of this one-photon resonance on phase-matching, absorption and the nonlinear yield. The efficiency of continuous Lyman-α generation has been improved by a factor of 4.5.
