Abstract
An injection-locked laser is disclosed. The injection-locked laser comprises a seed laser, an oscillator into which a certain component of light output from the seed laser is injected as seed laser light, a frequency converter which shifts a frequency of the remaining component of the light output from the seed laser, a photodetector which detects light obtained by synthesizing the light output from the oscillator and the light output from the frequency converter, and a controller which controls an optical path length of the oscillator based on a beat signal component contained in the signal output from the photodetector.
Claims10
An injection-locked pulsed laser comprising:
- a seed laser;
- an oscillator into which a first portion of light output from said seed laser is injected as seed laser light;
- a frequency converter which shifts a frequency of a second portion of the light output from said seed laser;
- wherein the second portion is different from the first portion;
- a photodetector which detects light obtained by synthesizing the light output from said oscillator and the light output from said frequency converter;
- and
- a controller which controls an optical path length of said oscillator based on a beat signal component contained in the signal output from said photodetector.
