Abstract
A Q switch resonator includes: an optical resonator comprising at least two mirrors, and configured to accumulate power of a continuous wave or an intermittent continuous wave incident from an outside; and a switching element provided in the optical resonator. The switching element is configured such that, when the power accumulated in the optical resonator increases to a predetermined level, the switching element outputs an optical pulse by lowering a Q factor from a first level to a second level lower than the first level.
Claims24
A Q switch resonator, comprising:
- an optical resonator comprising at least two mirrors, and configured to accumulate power of a continuous wave or an intermittent continuous wave incident from an outside, wherein the optical resonator does not contain a gain medium;
- and
- a switching element provided in the optical resonator, wherein:
- the switching element is configured such that, when the power accumulated in the optical resonator increases to a predetermined level, the switching element outputs an optical pulse by lowering a Q factor from a first level to a second level lower than the first level.
A pulse generator, comprising:
- a first optical resonator, wherein the first optical resonator does not contain a gain medium;
- and
- a light source configured to cause a continuous wave or an intermittent continuous wave to be incident on the first optical resonator, wherein:
- the first optical resonator comprises a first switching element, and
- the first switching element is configured such that, when power of light incident on the first optical resonator increases to a predetermined level, the first switching element outputs an optical pulse by lowering a Q factor of the first optical resonator from a first level to a second level lower than the first level.
A pulse generator, comprising:
- a first optical resonator;
- a light source configured to cause a continuous wave or an intermittent continuous wave to be incident on the first optical resonator;
- and
- a second optical resonator connected to an output of the first optical resonator, wherein:
- the first optical resonator comprises a first switching element, and
- the first switching element is configured such that, when power of light incident on the first optical resonator increases to a predetermined level, the first switching element outputs an optical pulse by lowering a Q factor of the first optical resonator from a first level to a second level lower than the first level, and
- a resonator length of the second optical resonator is shorter than a resonator length of the first optical resonator.
