PURPOSE:To eliminate the effect of a resonance phenomenon by a method wherein, when a BSO or BGO single crystal is Z-cut and the work size measures l length X w(mm.) width within a surface perpendicular to a Z-direction, it is set to[(1/l<2>)+(1/w<2>)]<1/2>> 0.68(1/mm.). CONSTITUTION:So called standard pulse waveform, having a rise time 1musec and a fall time 40musec, is often used in a high-voltage application field, but in order to measure a standard pulse waveform by a sensor, a resonance frequency is needed to be at least 500kHz or more. It order to obtain a photo application voltage sensor having a high resonance frequency of 500kHz or more, and when a BSO crystal is Z-cut to measure l length X w(mm.) width within a surface perpendicular to a Z-direction, it may be set to[(1/l<2>)+(1/w<2>)]<1/2>>0.68(1/mm.), and this eliminates the effect of a resonance phenomenon due to a surface slip. |
