Iranian Knowledge-Based Firm Produces Atomic Vapor Cells
“The atomic vapor cell is made of glass, inside which is rubidium atom vapor, and our colleagues were able to produce it for the first time in Iran,” said Neda Roustayee, a post-doctoral researcher from Shahid Beheshti University and a member of the knowledge-based Hesgarsazan Nogostar company.
Noting that the Iran-made atomic vapor cell has a low price compared to foreign models and can be produced in different geometries, she said, “This product is used in brain imaging, brain magnetic field measurement, atomic clock, and atomic and quantum projects.”
“The transitions of this product have been measured and produced for the first time with excellent quality in Iran. At present, this product has been commercialized and given the fact that it is widely used in Iran’s quantum industry, it has been produced,” Roustayee said.
A Vapor Cell is a box of atoms or molecules. Vapor Cells can be measured with a laser and can form the hearts of many quantum sensors and standards.
As atoms are fundamental structures composed of fundamental particles, their energy level structures form the basis of many practical realizations of absolute frequencies and wavelengths.
In a generic atomic vapor cell, a laser (at top, white) sends light through a population of atoms (blue-gray dots) trapped in an airtight cell (dark gray).
Properties of the light change as it passes through the atoms, and the result is detected by a sensor (red spot on yellow rectangle).
