Infrared Detection By Tl-Ba-Ca-Cu-O Superconducting Films

Zusammenfassung

The response of polycrystalline Tl–Ba–Ca–Cu–O superconducting thin films on short laser pulses has been investigated for radiation between 10 mgrm and 500 mgrm wavelength. Fast signals with time constants less than 1 ns were observed for wavelengths longer than about 100 mgrm whereas for shorter wavelengths only a bolometric signal could be detected.
