摘要：
The response of a high T-C dc SQUID under light (780nm) has been investigated. In a first experiment the beam was applied in order to cover the whole SQUID washer and produce a maximum reduction of the critical current up to 7%. The resulting sensitivity is low to be useful. In the second experiment. The spot was then applied only on one arm of the SQUID ring. It induces a circulating current as in the BLUZER's QSKID, and we have measured a responsivity about 200 phi(0)/Watt associated to kinetic inductance variations. That value is consistent with the BLUZER's theory and we further discuss the possible improvements of sensitivity and N.E.P..
