a, Schematic diagram of the HCF-LN-CPPLN experimental setup. W, CaF₂ window; M, mirror. b, The bright white-light circular spot emitting from the CPPLN sample. c, The 1st-order diffraction beam of b, showing a colorful rainbow pattern from violet to red. d, Normalized spectrum of the output full-spectrum laser signal generated by the HCF-LN-CPPLN module via synergic 2nd-NL HHG and 3rd-NL SPM effects as estimated by a criterion of −25 dB. Note that the spectrum has been normalized against the maximum value.
