Question
The plane-parallel geometry for these devices is much more sensitive to misalignment compared to the concentric geometry. For 10 points each:
[10m] Name these devices, which comprise the “buncher” and “catcher” of a klystron. The modes of these devices determine which wavelengths experience the greatest power increases.
ANSWER: optical cavity [or optical resonator or cavity resonator or resonant cavity; reject “lasers”]
[10e] The resonant cavity of these devices allows the light beam to repeatedly pass through a gain medium, gaining power with each trip.
ANSWER: lasers
[10h] The alignment of optical elements in a laser resonator can be checked using one of these devices, which fire a light ray with nearly zero beam divergence at a mirror, then assess the deflection of the returned image to give very precise measurements of angles.
ANSWER: autocollimators
