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 Encyclopedia of Laser Physics and Technology. Note that in some cases more than one answer is correct.

Question 31

If we attenuate a laser beam (e.g. by sending it through an absorber), will that modify its relative intensity noise?

(a) No. The power fluctuations relative to the average power will remain unchanged.

(b) Yes. The relative power fluctuations will increase, since we have to consider the squares of the power deviations.

(c) It depends. Relative intensity noise near the shot noise level will be increased, much stronger intensity noise will not.
