摘要:

The fundamental, quantum phase noise limited Lorentzian linewidth was directly measured from the beat‐note spectra generated by heterodyning PbS1−xSexdiode lasers with a stable CO gas laser. The experimental results were matched by calculated theoretical line profiles. Linewidths as narrow as 22 kHz full width at half‐maximum power were observed.
