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 13

How does absorption of the idler wave in the crystal of an OPO or OPA affect the efficiency of the device?

(a) not at all, if only the signal output is of interest; only heating of the crystal could hurt the efficiency by disturbing the phase matching

(b) the efficiency can be severely degraded, even without thermal effects
