Abstract
A laser diagnostic device may include a beamsplitter to split one or more input pulses into one or more fundamental pulses and one or more perturbing pulses, one or more beam-combining optics to combine the fundamental and perturbing pulses at a detection plane, a detector including a solid-state material at the detection plane, and a controller. The controller may receive a detector signal from the detector is indicative of nonlinear absorption in the solid-state medium of the fundamental pulses that is perturbed by the perturbing pulses. The controller may further extract a temporal electric field waveform of the one or more input pulses from the detector signal and provide as an output at least one of the temporal electric field waveform, a spectrum, or a spectral phase of the one or more input pulses.
