摘　　要：A high-brightness ultrabroadband supercontinuum white laser is desirable for various fields of modern science.Here,we present an intense ultraviolet-visible-infrared full-spectrum femtosecond laser source(with 300–5000 nm 25 dB bandwidth)with 0.54 mJ per pulse.The laser is obtained by sending a 3.9μm,3.3 mJ mid-infrared pump pulse into a cascaded architecture of gas-filled hollow-core fiber,a bare lithium niobate crystal plate,and a specially designed chirped periodically poled lithium niobate crystal,under the synergic action of second and third order nonlinearities such as high harmonic generation and self-phase modulation.This full-spectrum femtosecond laser source can provide a revolutionary tool for optical spectroscopy and find potential applications in physics,chemistry,biology,material science,industrial processing,and environment monitoring.
