The possibility of controlling the parameters of microwave signals by pulsed optical heating of ferrite film in a magnetostatic wave transmission line is demonstrated. Variations of the phase shift by 10 π rad, a delay time of 35 ns, and a signal power of 5 dB were obtained for a 5.7 GHz signal at a laser pulse energy of ~30 mJ
