Abstract

This paper presents a new design and measured data of a femtosecond streak camera. In order to reduce the temporal dispersion of photoelectrons in the new streak tube, an acceleration electric field near the photocathode was achieved to 8.75 kV/mm applying a high voltage pulse to the dc biased-photocathode. We have developed a high speed deflection circuit and a meander-type traveling wave deflector, and obtained high sweep speed of 8.76 X 10⁸ m/s on the phosphor screen. A temporal resolution of 180 fs was obtained with 100 photoelectrons using colliding-pulse passively modelocked ring dye laser for the light source. Dynamic ranges of 10 and 20 were achieved at the temporal resolutions of 200 fs and 330 fs, respectively.
