Аннотация:The approach of variational measurement is applied to the cavityless dissipative coupling (when test mass displacement changes transmittance of a single mirror). The result obtained is compared to the cavityless dispersive coupling (when the mass of the displaced single mirror changes the phase in the reflected wave). These types of coupling are compared for ponderomotive squeezing. In addition, the cavityless variant of combined dissipative and dispersive coupling is explored. It is established that combined coupling results in a stable optical rigidity even in the case of a single pump. Finally, it is confirmed that variational measurement can be applied to combined coupling.
