The formation of an electron–hole plasma during the interaction intense femtosecond laser pulses with transparent solids lies at heart processing. Advanced micro- and nanomachining applications require improved control over excitation characteristics. Here, we relate emission low-order harmonics to strong laser-field-induced formation. Together a measurement total density, identify contribution two competing ionization mechanisms─strong-field electron-impact ionization.
