Title:
Q SWITCH RESONATOR, AND PULSE GENERATOR
Document Type and Number:
WIPO Patent Application WO/2021/010089
Kind Code:
A1
Abstract:
Provided are a Q switch resonator that realizes efficient pulse extraction, and a pulse generator in which the Q switch resonator is used. The Q switch resonator has: an optical resonator that is formed by at least two mirrors, the optical resonator storing power of continuous waves or intermittent continuous waves incident from outside; and a switching element provided to the optical resonator. When the power stored in the optical resonator increases to a prescribed level, the switching element outputs a light pulse by lowering the Q value from a first level to a second level that is lower than the first level.
