Studying the possibility of creating a stable interference pattern along laser radiation in air or in a gas similar to artificial fog.
The goal is to obtain an interference pattern along the 440-450 nm laser radiation using multimode laser radiation (it is possible to use single-mode radiation in the visible spectrum of class 3 laser diodes.)
The main criterion for the experiment should be a clear distinction between bright and “dark” regions along the laser radiation.
Suggested gas: air or artificial smoke
Estimated length of the laser beam, where stable interference should be observed 50-100 cm
Highlight Length: 1-10cm
The length of the dark area is 1-10 cm.
Distribution of bright and dark area: arbitrary.
Ability to control the length of the bright and dark area.
The result of the calculation should be a function that can be used to produce the required crystal / material by a binary method, with which it will be possible to obtain a stable interference pattern. Parameters for the plate manufacturer must be provided (lithographic method)
