for a phase conjugated interaction through degenerate four wave mixing, such as

occurs in a saturable absorber dye jet as in Fig. 13.12 [88]. This lock-in problem

will be dealt with in more detail in Section 13.3.3.1 to follow.

13.3.2.2. Acceleration

We have seen in the previous section that the ring configuration of Fig. 13.12

leads naturally to a form of inertial sensing of rotation. Similarly, the linear

configuration of Fig. 13.13 has an inertial response as accelerometer. Let us

consider indeed that the whole laser is accelerating along the direction BA (the

laser cavity is rigid, and the distance from A to B is L). ...
