GaAsP photocathode

Timing problems can be avoided by using PMTs with high-efficieney GaAsP photocathodes, such as the Hamamatsu H7422-40 module [214]. The modules have a stable and almost wavelength-independent transit time spread of about 300 ps duration (see Sect. 6.4.2 page 245). The quantum efficiency reaches 40% at... [Pg.184]

For a two-photon microscope the situation is even more complicated. Even if the NIR blocking filter is removable, a detector with a biaUcali or GaAsP cathode is insensitive at the laser wavelength. Of course, by increasing the laser power something is detected in any PMT. However, in the NIR a photocathode for the... [Pg.158]
