研究了可见光与软x射线的相位匹配谐波转换，利用近年来发展起来的导波频率转换技术将800纳米的光提升到17 ~ 32纳米的范围。与非相位匹配的情况相比，该过程增加了相干x射线输出的10(2)到10(3)倍。该源使用小型（亚毫焦耳）高重复率激光器，将使线性和非线性x射线科学中的各种新实验研究成为可能。
Phase-matched harmonic conversion of visible laser light into soft x-rays was demonstrated, The recently developed technique of guided-wave frequency conversion was used to upshift light from 800 nanometers to the range from 17 to 32 nanometers. This process increased the coherent x-ray output by factors of 10(2) to 10(3) compared to the non-phase-matched case. This source uses a small-scale (sub-millijoule) high repetition-rate laser and will enable a wide variety of new experimental investigations in linear and nonlinear x-ray science.
