| Abstract | Optical amplification of the detection laser light seems an elegant method to improve the sensitivity of a system for the optical detection of ultrasound. However, the amplified spontaneous emission associated to the optical amplification process is a source of both phase and intensity noises. Two configurations are possible, one with the amplifier located ahead of the inspected surface (preamplification) and one after (post-amplification). We discuss the advantages and drawbacks of these two schemes when a photorefractive two-wave mixing demodulator is used. |
