“…4 and 6 represent model calculations with parameters shown in Table 1. The model calculations are based on a completed solution of the electromagnetic field created in the sensor by the interfering light waves and are described in detail in [9]. The model takes into account the full light path between sensor and mirror in case of MichelsonMorley geometry and between beam splitter and sensor in case of Sagnac geometry.…”

“…1 left). Recently [9] it has been shown that the absorption of light in such sensors can be different when the standing waves are created by first splitting the beam and then redirecting the splitted beams so that they travel in opposite directions through the sensor. This is denoted as Sagnac geometry (see Fig.…”

“…1 right). In [9] the absorption was measured by a reduction of the transmitted intensity. Here, the response is measured by means of simple standing wave sensors based on amorphous silicon deposition on a glass substrate.…”

Optical standing wave sensors have been manufactured by amorphous silicon deposition. The responses of these sensors, when subjected to standing waves, have been calculated and measured. It is shown that the responses are different depending on the way the standing wave is created. The responses also depend on the thickness and material properties of the layers used to create the sensors. Quantitative agreement between measurements and model calculations can be obtained by including alignment errors, incoherent light interaction and scaling factors. The simple construction of the sensors allows for a broad application range.

“…So that the coherence patterns would vary the refractive index of the fiber core, an absorption dynamic fiber grating was formed in the SA fiber to elect the longitudinal mode [14,18]. After that PC2 was emplaced nearby the active fiber to prevent the two counterpropagating waves in the linear cavity from forming standing waves [19]. This was to suppress the multilongitudinal-mode oscillations to some extent, which were caused by the SHB effect [20,21].…”

A high-slope-efficiency single-frequency (SF) ytterbium-doped fiber laser, based on a Sagnac loop mirror filter (LMF), was demonstrated. It combined a simple linear cavity with a Sagnac LMF that acted as a narrow-bandwidth filter to select the longitudinal modes. And we introduced a polarization controller to restrain the spatial hole burning effect in the linear cavity. The system could operate at a stable SF oscillating at 1064 nm with the obtained maximum output power of 32 mW. The slope efficiency was found to be primarily dependent on the reflectivity of the fiber Bragg grating. The slope efficiency of multi-longitudinal modes was higher than 45%, and the highest slope efficiency of the single longitudinal mode we achieved was 33.8%. The power stability and spectrum stability were <2% and <0.1%, respectively, and the signal-to-noise ratio measured was around 60 dB.

“…This detector could measure the intensity of a light beam in a standing wave. This detector could not be reproduced, so a program was carried out to construct a standing wave detector based on amorphous silicon layer on a glass substrate [19,20]. It was shown that a successful standing wave detector could be constructed.…”

Some of these experiments are reviewed and analyzed.Unfortunately, many experiments are not of high quality, never repeated and mostly both. Results of repetition of several experiments (Silvertooth, Cahill) is reported and results of a new experiment based on the idea that the conductivity of a material depends in first order on the velocity of the material with respect to the ether will be presented. It is proposed that the most promising experiments should be repeated, under which the experiments performeН bв Demjanov Тn tСe 1λθ0's.
