  We present a concept of a tunable optical excitation of spin waves and
filtering their spectra in a ferromagnetic film with 180$^{\circ}$ N\'eel
domain wall. We show by means of micromagnetic simulation that the fluence of
the femtosecond laser pulse and its position with respect to the domain wall
affect the frequencies of the excited spin waves, and the presence of the
domain wall plays crucial role in control of the spin waves' spectrum. The
predicted effects are understood by analyzing the changes of the spin waves'
dispersion under the impact of the laser pulse.
