AbstractUsing available multiwavelength data for the pulsars of different ages detected in the optical range, we analyze the efficiencies of the conversion of the pulsar spindown power E ˙ into the observed non-thermal luminosity L in different spectral domains. We find that these pulsars show significantly non-monotonic dependencies of the optical and X-ray efficiencies ( η = L / E ˙ ) versus pulsar age with a pronounced minimum at the beginning of the middle-age epoch (∼104yr) and comparably higher efficiencies of younger and older pulsars. In addition, we find a strong correlation between the optical and 2–10keV X-ray luminosities of these pulsars that implies the same origin of their non-thermal emission in both spectral domains.
