Abstract

On the basis of the recently developed PV-FS-type femtosecond streak tubes supplied with the original photocathode-accelerating mesh assembly (dedicated for pulse operation) and ultra-sensitive high frequency deflection system, the experimental prototypes of a 200 fs streak camera was designed, manufactured and tested. The camera experimental time resolution > 200 femtosecond, its maximum spatial resolution along the slit direction is better than 30 line pairs/mm in dynamic mode. The range of the streak duration along the 25 mm output screen is from 50 ps to 5 ns, which corresponds to the streak speeds of 5 × 10¹⁰ - 5 × 10⁸ cm/s. The camera triggering delay is 50 ns with ± 20 ps jitter at triggering signal of 5 Volts/50Ohm/1ns rise time with the maximum repetition rate of 100 Hz. At the maximum time resolution the dynamic range is about 10. The spectral range of the recorded optical events may cover 115 - 1550 nm. The typical optical radiation intensity at 800 nm needed to illuminate the input photocathode in order to get maximum time resolution is 500 Watts/cm².
