Abstract
The invention is a frequency stabilized passive Q-switch laser, which has the advantages of small volume, simple structure, no need for high power voltage, etc. It has been a long time that timing jitter in conventional lasers is so large that they can not be applied to fields such as distance measurement. This invention utilizes an optical external modulation method to stabilize the repetition rate of the passive Q-switch, and thus to decrease its timing jitter. At the same time, the repetition rate of the Q-switch laser can be controlled by the same technology to meet various application needs.
