Kastler discovered that by irradiating atoms with specially polarized light, he could push electrons into higher energy levels, effectively "pumping" them into a specific, ordered state.
Alfred Kastler's legacy is the mastery of light-matter interaction. His work ensures that every time we use GPS or rely on high-precision measurements, we are benefiting from the quiet revolution he started in a Parisian laboratory. alfred kastler

Kastler’s work laid the groundwork for modern atomic clocks, the most precise timekeeping devices known, which are essential for GPS technology. effectively "pumping" them into a specific
