Paper Abstract

We describe a new design and measure data of a femtosecond streak camera with an electromagnetic focusing type streak tube. In order to reduce the temporal dispersion of photoelectrons in the 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 measured data 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.
