Fig. 5: Intense high-flatness 7-octave DUV-FIR pulse white laser.
From: mJ-level 7-octave ultraflat white laser encompassing 200–25,000 nm
a Synthesis of up-conversion and down-conversion white laser into DUV-FIR full-spectrum white laser. b The power spectral intensity of the MIR laser from the HCF setup and the HCF-LN module, respectively. A baseline of 10 dB is shown for the assessment of spectral flatness. c The photon flux spectral intensity of the generated full-spectrum white laser spanning from 200 to 25,000 nm with an output pulse energy of ~1 mJ and an estimated pulse duration of 1.8 ps
