Abstract

A low noise preamplifier for a photodiode detector of short laser pulses has been designed and constructed. The photodiode amplifier configuration has within the long wavelength bandwidth a NEP value of O. 64pWHf112. The dark output noise of the photodiode is 2. lnVHz112 the bandwidth is 6. 4MHz. An analysis of noise from different elements of the amplifier as well as a description of voltage and bandwidth optimization are presented.
