"cheaper, emitting single color/ frequency for ultra low-noise, stable light for ultra-precise atom measurement/ control... passing laser through rubidium atomic vapor, a near IR transitions to stable atomic linewidthsr... Fabry-Perot laser diode, resonator, silicon nitride platform... 4 orders magnitude better... cold atom quantum sensors (gravimeters/ 2-photon atomic clocks), portable field-deployable/ space-based quantum and cold-atom interferometer sensors, quantum computing with neutral atoms/ trapped ions"
