SUMMARY
The coherence length of a highly stabilized He-Ne laser, with a frequency stability of 2 parts in 1010, can be calculated using the formula for coherence length, which is c/delta frequency. Given the wavelength of 632.8 nm, the coherence time is determined by the inverse of the delta frequency. The discussion clarifies that 1010 refers to the frequency's stability, indicating an uncertainty of ±(2*f*(10-10)), where f is the laser's frequency.
