Abstract
The manifestation of a superconducting pp DELTA in optical spectra for frequencies omega much greater than DELTA/HBAR corresponding to inter band transitions is studied. A characteristic structure in the differe nce spectrum of the superconducting and normal phases, with its width connected with DELTA, is predicted. Experimental manifestations of the predicted effect are discussed. The results of femtosecond spectrosco py of YBa2Cu3O7-delta films are analyzed in the light of the present s tudy.
