I am looking for clarification of the wording used in a recent article about X-ray lasers. https://www6.slac.stanford.edu/news...slac-could-make-x-ray-lasers-more-stable.aspx ... researchers have been trying to generate higher and higher harmonics, with the goal of reaching X-ray wavelengths of 10 nanometers or less. ... “We’ve now reached the infrared laser’s 75th harmonic, which allows us to produce microbunches able to generate light with a wavelength of 32 nanometers,” ... I assume they mean they have bunched the electrons into 32 nanometer bunches, producing photons over a distance of 32 nanometers, but that the actual individual photons produced within the bunch probably have a wavelength much shorter (maybe as small as 0.1 nanometers or whatever). I find the use of the wording "generate light with a wavelength of 32 nanometers" to be confusing if not misleading.
