Abstract
This work studied the emission of XUV radiation from water microdroplets under excitation with either a single or a pair of intense femtosecond laser pulses (Ti:Sa, 80 fs, ∼1014 W/cm2 , 800 nm, 1 kHz). When varying the delay between the two pulses a transition from pure incoherent plasma emission to coherent high-harmonic generation was observed. Under optimized conditions high-harmonic radiation up to the 27th order was obtained.
