Real-time oscilloscope observation of an ultrafast photodiode response to mode-locked laser pulses
TLDR
In this paper, the authors used a direct current to 5 GHz real-time oscilloscope to display 100 ps full width at half maximum (FWHM) pulses on a photodiode.Abstract:
Pulses of 100 ps full width at half maximum (FWHM) have been displayed on a direct current to 5-GHz real-time oscilloscope. The 100-ps duration includes contributions from the oscilloscope, the photodetector, and the laser pulse,Maximum current in the linear regime of the photodiode is ≈3 amperes so that electric pulses of ≈70 ps FWHM and ≈150 volts can be obtained with the laser-detector combination. Results of a simple optical method for determining the exposure time of high-speed electronic cameras are also briefly given.read more

A New Technology for Transferring Photocathodes
P. Dolizy,R. Legoux +1 more
TL;DR: In this article, a new technology for transferring photocathodes is described, where the substrate on which the photoemissive layer is to be formed, is isolated from all other component parts of the photoelectric tube, so that it alone is exposed to the materials evaporated during the processing of the photocathode.
