Vladislav I. Pustovoit Russian Academy of Science Scientific and Technological Centre of Unique Instumentation

2 A Basis For Gravity Waves Detection
Fabri-Perot Resonator With Periodic Structures As Reflecting Mirrors Being A Basis For Gravity Waves Detection

3 (Laser Interferometer Gravitation Waves Observatory)
LIGO (Laser Interferometer Gravitation Waves Observatory) Mirrors Laser l = 4 км PMT R=

4 Main problem - mirrors with reflection coefficient more, then

5 Main physical ideas-resonance transmitting wave
or particle E particle x

6 Particle resonance transmitted
Quantum system E0, то If E = E0 Particle resonance transmitted E0 E With probability ~ 1 Е.Wigner,1933, G.Bete P. Paierls, 1935.

7 Resonant tunneling of surface phonons
Resonator F-P for SAW ~ R

8 Fabri-Perot Resonator With Periodic Structures As Reflecting Mirrors
Reflection coefficient for Fabri-Perot resonator Reflection coefficient for one periodical structure А.М.Афанасьев, Ю.В.Гуляев, В.И.Пустовойт, РТЭ, г.

9 Transitted function Fabri-Perot resonator
LIGO T Transitted function Fabri-Perot resonator

11 Transmitted function where

12 Conditional resonance transmitted

13 Transmitted function = E where

14 Transmitted functional
0.01 <  <

15 Transmitted functions

17 T if Half-width transfer function usuial F-P
Interferomers and resonant tunneling will be equivalent if

18 Optical schema for detecting GW
splitter laser PMT mirror Fabri-Perot resonators

19 Periodical structures
Interference term Amplitude GW Distance between Periodical structures where Amplitude of EW In resonance conditional, phase is
