abstract="Nonequilibrium picosecond and bolometric responses of YBCO films 500 angstroms thick patterned into 20 X 20 micrometers $^{2}$ size structure to 17 ps laser pulses and modulated radiation of GaAs and CO$_{2}$ lasers have been studied. The modulation frequencies up to 10 GHz for GaAs laser and up to 1 GHz for CO$_{2}$ were attained. The use of small radiation power (1 - 10 mW/cm$^{2}$ for cw radiation and 10 - 100 nJ/cm$^{2}$ for pulse radiation) in combination with high sensitive read-out system made possible to avoid any non-linear transient processes caused by an overheating of sample above a critical temperature or S-N switching enhanced by an intense radiation. Responses due to the change of kinetic inductance were believed to be negligible. The only signals observed were caused by a small change of the film resistance either in the resistive state created by a bias current or in the normal state. The data obtained by means of pulse and modulation techniques are in agreement. The responsivity about 1 V/W was measured at 1 GHz modulation frequency both for 0.85 micrometers and 10.6 micrometers wavelengths. The sensitivity of high-T$_{c}$ fast wideband infrared detector is discussed.",
