Subhertz-linewidth Nd:YAG laser

Optics Letters, 2004
Light from a Nd:YAG laser at 1064 nm is independently stabilized to two Fabry-Perot etalons situated on separate vibration-isolation platforms. A heterodyne beat measurement shows their relative frequency stability to be at the part-in-10(15) level at 5 s and the relative linewidth to be less than 1 Hz.

Narrow-Linewidth Fano Laser

Conference on Lasers and Electro-Optics, 2022
By exploiting Fano resonances, a microscopic laser with a linewidth >20 times smaller than previous microscopic lasers is experimentally demonstrated. We also show that the linewidth can be further improved by engineering the Fano lineshape.

Commutation relations and laser linewidth

Physical Review A, 1990
The waves reflected from a resonator must obey the commutation relations of waves in free space. This fact alone, regardless of whether the medium in the resonator is linear or nonlinear, imposes commutation relations on the internal noise sources. The minimum linewidth of an oscillator can be derived from this fact alone.
