The photoresponse of a YBaCuO/ZrO 2 bolometric structure was measured under modulated (λ = 630 nm) and pulsed (τ ≈ 7 – 8 ns; λ = 337 nm) laser excitation. The shape of the measured photoresponse was interpreted by a thermal model; nevertheless, the pulse amplitude for vanishing YBaCuO film resistance was 5–6 times greater than predicted; the thermal boundary resistance R Bd between YBaCuO and YSZ was evaluated ⋍ 10 −2 K × cm 2 /Watt, which is considerably larger than estimated theoretically for the similar situation of YBaCuO/MgO [5].
