Cover Story：Liu H H, Yu Y, Song W, Jiang Q, Pang F F. Recent development of flat supercontinuum generation in specialty optical fibers. Opto-Electron Adv 2, 180020 (2019).
Supercontinuum (SC) laser sources exhibiting excellent wide bandwidth and good beam quality have attracted much attention because of their potential applications including spectroscopy, optical coherence tomography, chemical detection, biomedicine, as well as homeland security, etc. The research group of Liu Huanhuan from Shanghai University is dedicated to studying the effects of initial pulse center wavelength, peak power, initial pulse width, chirp, as well as nonlinear effects in nonlinear fibers on SC flatness. Through continuous improvement, at present, they have realized SC generation with a good spectral flatness with fluctuation of less than 1.29 dB and the obtained SC source has potential application value in the optimization of deep biological imaging in short-wave infrared region.
