Morphology

ultrashort = short (transparent) = ultra + short

The meaning is a regular intensification of 'short' with the prefix 'ultra-', so a learner can infer 'extremely short'.

Etymology

Ultrashort combines the part ultra- and the word short, where ultra- means 'beyond' or 'extreme', as in ultraviolet. So ultrashort is 'far shorter than usual', which fits uses like very short bursts of time or very short wavelengths.
