Considerations and Calculations for Application of an Optical Amplifier as an End- and Preamplifier

摘要

The simultaneous application of an optical amplifier for outgoing laser pulses and as a preamplifier for such pulses, which are reflected from a target are discussed. The calculations show that such application is possible, when definite time differences between outgoing pulses and reflected ones are kept. Calculations for the signal to noise ratio of preamplifiers are given.
