New femtosecond streak camera with temporal resolution of 180fs
- Hamamatsu Photonics K.K. (Japan)
The authors described a new design and measured 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 8.75kV/mm applying a high voltage pulse to the D.C. biased-photocathode. They have developed a high speed deflection circuit and a Meander-type traveling wave deflector, and obtained high sweep speed of 8.76{times}10{sup 8} m/s on the phosphor screen. A measured data of 180fs was obtained with 100 photoelectrons using colliding-pulse passively modelocked ring dye laser for the light source. Dynamic ranges of 10 to 20 were achieved at the temporal resolutions of 200fs, 330fs respectively.
