The discussion revolves around the concept of harmonics in the context of lasers and light, drawing parallels to sound frequencies. The original poster questions whether a laser operating at a specific wavelength, such as 500 nm, can have harmonics similar to sound waves.
The conversation includes varying perspectives on the existence of harmonics in lasers. Some participants suggest that while lasers typically operate at a fundamental frequency, there are exceptions, such as certain laser pointers that may exhibit harmonic behavior.
There is mention of theoretical versus practical considerations regarding the production of standing waves with light, indicating a complexity in the discussion that remains unresolved.

Hi all.
When talking about sound, we tak about the fundamental frequency, the first harmonic, second, third etc.
Does this also work for lasers, i.e. for light? So if I have a laser at 500 nm, then the third harmonic is 3 times the frequency that corresponds to 500 nm?
