Fig. 5: Spectral stability and the energy scaling of the SC laser.

From: Stable, intense supercontinuum light generation at 1 kHz by electric field assisted femtosecond laser filamentation in air

Fig. 5

a The white light spectra after filamentation with (FIL+55kV) and without (FIL) DC electric field. The initial laser spectrum (no FIL) is for comparison. Each spectral distribution was normalized at its maximum. b The SNR of the SC spectral intensities under different applied voltages. The laser worked at 1 kHz. c The SC laser energy obtained as a function of pump laser energy under 1 m focusing condition
