High Dynamic Range Streak Camera C7700 L The relaxation oscillation of a laser diode can be measured with the C7700 under single shot operation. (The data was captured with a C4880-21 readout CCD camera.) Less than 60 ps The C7700 is a newly developed high dynamic range streak camera that can handle a large number of photo- electrons. This feature enables single-shot measurements of ultrafast phenomena with a D-range as high as 10 000 : 1. This system is suitable for high-precision simultaneous measurement of high-intensity and weak intensity pulse light. 10 000 :1

(where electrons are swept in the direction from top to bottom) [Operating Principle] The light pulse to be measured is focused onto the photocathode of the streak tube through the slit, where the photons are con- verted into a number of electrons proportional to the intensity of the incident light. These electrons are accelerated and conducted towards the phosphor screen, and a high-speed voltage which is synchronized to the incident light is applied. The electrons are swept at high speed from top to bottom, after which they are bom- barded against the phosphor screen of the streak tube and con- verted to an optical image. When the light intensity of the streak image is very weak, an image intensifier or an image booster amplifies the low light level streak image. ∆OD = 0.1 0 12 34 5 Time (ns) S1 - Sn absorption ∆λ = 482 to 489 nm T1 - Tn absorption ∆λ = 557 to 581 nm L The 266 nm excitation (25 ps, 0.2 mJ, 2 mm focused, single shot) of Chrysene in THF (0.5 mmol/l) D-range of 10 000:1 of ultrafast phenomena under single-shot operation

FEATURES

G High dynamic range of 10 000:1* G Temporal resolution of 5 ps* G Effective photocathode size: 17 mm G Simultaneous measurement of light intensity on temporal and spatial (wavelength) axis G IEEE 488 (GP-IB) control *[About a Dynamic Range] The maximum dynamic range of the streak camera essence is set to 1000:1 by the measurement condition of temporal resolution 5ps, and is set to 10 000:1 by the measurement condition of temporal-resolution 100ps. With a light intensity, the image intensifier tube, such as an image intensifier or an image booster, is combined with a streak camera. In this case, the image intensifier tube may restrict the dynamic range of the measurement system. Furthermore, a read-out camera may also restrict the dynamic range of the measurement system.

It enables precise, quantitative acquisition and preanalysis of two dimensional streak data that includes photon counting plus a full range of data correction and calibration possibilities. The HPD-TA allows the remote control of the C7700 via GPIB interface.
