The Photonics Quiz

Test yourself by solving a set of questions concerning laser technology, optical fibers, and nonlinear optics! The following questions are mostly solvable by using the RP Photonics Encyclopedia. Note that in some cases more than one answer is correct.

Question 10

Are the lines in the spectrum of a continuous-wave laser exactly equidistant?

(a) yes, the line spacing is the inverse round-trip time, which is constant

(b) no, because there is generally some amount of chromatic dispersion

(c) no, because higher-order transverse modes have modified resonance frequencies (assuming that such modes are excited)
