Title: Electric signal measuring device
Inventor: HASEGAWA NOBORU
IPC: H01L21/66
Filed: 1992-02-14
Abstract: PURPOSE:To measure the title ultra high-speed electric signal in high sensitivity by making use of the second resonance high harmonic waves aroused on an inversion asymmetrical crystal on the surface thereof in relation to the evaluating method of a photoconductive element. CONSTITUTION:The femto second laser 1 beams are divided into pulse 3 and pulse 4 with a time lag given thereto by a beam splitter 2 so as to be focussed by a lens 5. The pulse 3 passing through a wavelength conversion element 13 is focussed on the gap of photoconductive element to generate a voltage pulse in femto second while the pulse 4 is irradiated over the space between transfer lines to generate the second high harmonic waves. At this time, the intensity of the second high harmonic waves is changed by the polarization caused by the existing potential between the transfer lines. That is, the laser and the substrate material can be selected to make the laser wavelength two times of the wavelength of the absorption band of the substrate material to arouse a resonance thereby enabling the intensity of the aroused second high harmonic waves to be increased.
